DE102008038121A1 - Liberating aromatics from organic compounds by chemically exothermic process and pyrolytic processes, involves providing carbonate-salts as carbonate gas sources, which are selected from different granule size distributions - Google Patents

Abstract

Aromatics liberation involves providing carbonate-salts as carbonate gas sources, where the carbonate-salts are selected from different granule size distributions. The sizes are determined such that the salts indicate absolutely no decomposition tendencies before entering into pyrolytic periphery by their specific thermal absorption from irradiation part. The sizes start to decompose by contact heat transfer and radiation part during entering into the zones. The aromatics liberation is accomplished by providing carbonate-salts as carbonate gas sources, where the carbonate-salts are selected from different granule size distributions. The sizes are determined such that the salts indicate absolutely no decomposition tendencies before entering into pyrolytic periphery by their specific thermal absorption from irradiation part. The sizes start to decompose by contact heat transfer and radiation part during entering into the zones. The reactions hinder generation schema of aromatics from the pyrolytic cracking products through liberated carbon dioxide in pyrolysis of metal carbonate salt decomposition. The aromatics is liberated from an organic base material by carbon dioxide heated by the thermal of pyrolysis process, which is supplied by a gas flow.

Description

The Innovation describes a process for the release of aromatics organic compounds by means of a chemically exothermic process, as well as pyrolytic processes and describes one alike simultaneous suppression of the formation schemes of aromatics in the presence of carbonaceous material such as CO2.

The Suppression of polyadditive carbon processes and hydrogen, hydrocarbons and the simplest organic Compounds is the state of the art in on the pollutants and combustion processes by means of exhaust gas recirculation known in the largest distribution. Likewise is This technology in the automotive industry about exhaust gas recirculation known, and now widely used.

In the exhaust gas recirculation, the exhaust gas, which usually consists of N 2, CO 2 and little CO, is mixed with fresh air, and fed back into the combustion process as mixed gas with enriched oxygen. In the process, the CO2, which is recirculated via the exhaust gas recirculation in the combustion process, unfolds from the declaration DE 103 20 067 described effects within the combustion processes.

It comes to a suppression until the avoidance of aromatics in the presence of carbonaceous material such as CO2. in pyrolysis processes, as well as pollination and combustion processes.

Of the DE 41 24 277 describes a thermal process for the decontamination of soils, which at 650C under exclusion of oxygen, remove the resulting by the thermal polycyclic aromatic hydrocarbons using a desorbent such as CO2 as solvent and carrier gas from the process.

In the flavor release is from the wine industry research, the FR-OS 25 05 868 and the EP-PS 00 77 745 As well as earlier references, it is already known to extract by natural alcoholic fermentation drinks such as wine flavorings as well as ethanol by a high-pressure extraction with carbon dioxide. Essentially, the two cited documents differ only in that they work in one case with liquid carbon dioxide and in the other case with carbon dioxide in the supercritical state. Both documents describe in detail these methods.

These By means of carbon dioxide desired flavor release is sufficient Gentle process, which the and extracted from it substances does not harm.

The topic of suppressing the formation of thermal aromas by means of catalysts such as salts or metal oxides has long been known from the tobacco industry:
From P 29 19 556.0 process is known to a tobacco blend, cigarettes, cigars and pipe tobacco manufactured therefrom and method for treating tobacco, wherein nicotine and the polycyclic aromatic hydrocarbons usually formed in the combustion of tobacco can be suppressed. The EP 02 792 448.9 and its PCT publication no .: WO 2003 10 53 177 from the 18.12.2002 describes the state of the art and clarifies also Verschwelungsreaktionen.

Problem:

It was a process for the release of aromatics from organic compounds by means of a chemically exothermic process and pyrolytic process to create the educational schemes of aromatics from pyrolytic Chrackprodukten hamper and at the same time from the thermals of the Pyrolysis liberated aromatics from an organic base material dissolves, but to be discharged a gas stream to be able to.

The general state of the art approaches have encouraged us to take a closer look at the formation process within pyrolysis:
It is known that numerous substances or substance combinations found in tobacco smoke are toxic. Examples of such unwanted tobacco smoke constituents are polycyclic aromatic compounds and their heterocyclic analogues.

The strong carcinogenic effects of some polycyclic aromatic hydrocarbons are known. Special polycyclic aromatic compound needs special attention. Benzenes and their compounds such as 1,2-benzopyrene as well as 3,4-benzopyrene and 4,5-benzopyrene. Thieves Special attention is therefore needed because this compound has been known for a long time as a highly carcinogenic agent. As well as toluene, phenol and their compounds.

to Reduction of levels of tobacco smoke to polycyclic aromatic Hydrocarbons have already been the most varied treatment measures carried out. So it is already known, tobacco with nitrates and to transfer nitrites. From FE-PS 1 180 320 is the addition from nitrites to tobacco and cigarette paper to reduce the (formed) amount of polycyclic aromatic hydrocarbons known.

From the U.S. Patent 3,121,433 the addition of potassium nitrate should be mentioned.

From the U.S. Patent 3,180,458 the addition of potassium and sodium nitrate to tobacco is known for reducing the formation of cigarette tar due to the accelerated burning rate of the cigarette.

The Treatment of tobacco blends with platinum group metals, e.g. As platinum, palladium, rhodium, osmium, iridium and ruthenium, to Reduction of tobacco smoke to active carcinogenic substances, is out the GP-PS 841 074 known.

Furthermore, attempts have been made to reduce the polycyclic aromatic compounds by means of zeolite molecular sieves. For example, from the U.S. Patent 3,292,636 Tobacco preparations are known in combination with molecular sieves of the L, X and Y series, synthetic or naturally occurring layered minerals. These sieves may have metals with catalytic activity with respect to organic conversion reactions.

From the U.S. Patent 3,572,348 For example, a smoke formulation with a zeolite material that effectively lowers the amount of polycyclic aromatic compounds formed upon combustion of tobacco is known. The zeolite material used has Y structure and has at least partially ion-exchanged zinc or contains metallic palladium. From the U.S. Patent 3,703,901 moreover, it is known that Y zeolites which have ion-exchanged Zn ions and contain platinum or silver are used to reduce the amount of polycyclic aromatic compounds in tobacco smoke.

Solution approach of the problem:

Our Investigations have shown that at a temperature above 550C a electrochemically active zone around the combustion zone, our pyrolysis-melting zone is formed. This zone is referred to in the literature as Langmuirzone described. Langmuirzonenprozessreaktionen were carried out by us with contact gases.

First we have the formation mechanism from pure CO2 gas to a reactive one Langmuirzone considered. The CO2 emits a zone gas, which causes the Carbon displaced from the Lanmuirzone, and contact chemical Polymer processes of the plasmatized hydrocarbon with chracked products hinders radicalized hydrocarbons.

there we found that a CO2-O2 gas mixture reacts on a reactive Langmuirzone an unpredictable quantum-mechanical interaction process triggers which of the literature was not apparent.

simplified represented one would assume that the oxygen means the interference effect with the CO2 does not affect the reaction affinity to other binding partners and the oxygen loses dissolves the CO2 as Langmuirkontaktgas.

It But first run off oxidation processes with carbon and the Pyrolytically cracked hydrogen is released unreacted the Langmuirzone, and seek newer in secondary reactions Binding partner, usually self or secondary oxygen.

The allows for a reactive interaction process of oxygen gas and close carbon dioxide gas in the plasmatized state.

We watched with surprise that this to the Langmuirzone introduced CO2 gas, which is thermally high reactivated, an extremely good solvent for Hydrocarbon and aromatics represents, and thereby leading blocked by aromatics to the electrochemically active Langmuirzone.

The Pyrolysis activates the CO2 gas and that causes the electrochemically activated CO2 gas is a greatly increased Has solvent power of aromatics.

From the FR-OS 25 05 868 and the EP-PS 00 77 It is well known that CO2 gas, taken in its own supercritical state, is already a good solvent for flavorings.

Pure CO2 gas is not a good solvent at normal temperature and conditions. Our solution to activate plasma plasma in a Langmuirzone in order to increase the solvent power against aromas was compared by another experiment:
CO2 gas was exposed to a barrier discharge to plasmatize it. The approach was verified. The solvent power of flavors in CO2 gas, which was excited via a plasma contact, is significantly higher than in the pure gas state.

Results and the graphical representation of the phenomena are on demand accessible to the examination procedure to the inventor height to support.

Within a flow reactor guided gas flow around the Pyrolysis and its surrounding Langmuirzone, it means in a pyrolysis of organic material with aromatics that the aromatic Ingredients of organic material by presence of CO2 before the pyrolytic zone and during the pyrolytic Process by the pyrolytically reactivated CO2 gas from the organic material removed, and taken with the gas stream. Also inhibits the formation of polycyclic aromatics such as benzene, Toluene and phenol.

For example This means in the smoldering of tobacco that the aromatic Ingredients of tobacco due to the presence of CO2 before the pyrolytic Zone and during the Verschwelungspyrolytischen process through the pollutant pyrolytically reactivated CO2 gas removed from the tobacco and with a vacuum gas stream is taken. There is also an inhibition of the formation of polycyclic aromatics such as benzene, toluene and phenol.

CO2 can be added to pyrolysis as follows:
By thermal decomposition of CO2 releasing or releasing substances such as carbonic acid salts such as marble (calcium carbonate) or soda (sodium carbonate), among others

These Salts are preferably soluble in the organic matter, (via a soda solution), so the organic Solid salt mixture (physical batch) pyrolyzed, or Dissolve or melt the salt in a face silicate capillary (and dried).

Sheet silicate particles like a layered mineral zeolite, an aluminum silicate, with a three-dimensional basic structure with the formula: XM2 / nO-Al203-YSi02-ZH20. M stands for an ion-exchangeable ion, usually a monovalent or divalent metal ion; n stands for the atomic valency of the (metal) ion; X and Y stand for Coefficients of metal oxide or silica; and Z stands for the number of water of crystallization. Examples of such zeolites close A-type zeolites, X-type zeolites, Y-type zeolites, T-type zeolites, high silica zeolites, sodalite, mordenite, Analcite, clinoptilolite, chabazite and erionite, one.

The Ion exchange capacities of these zeolites are as follows: A-type zeolite = 7 meqlg; X-type zeolites = 6.4 meqlg; Y-type zeolites = 5 meqlg; T-type zeolites = 3.4 meqlg; Sodalite = 11.5 meqlg; mordenite = 2.6 meqlg; Analcite = 5 meqlg; Clinoptilolite = 2.6 meqlg; chabazite = 5 meqlg; and erionite = 3.8 meqlg.

Also ceramic particles such as zeolites, hydroxyapatite, zirconium phosphates and other ion-exchanging ceramic materials, in particular the hydroxyapatite particles containing metals, as described in U.S. Patent No. 5,009,898 or zirconium phosphates containing metals, as described, for. Tie U.S. Patent No. 5,296,238 ; 5,441,717 ; and 5 405 644 can be used, can be used.

at In our experiments, we found that to be porous inert substances such as porous layered minerals such as zeolites or activated carbon salts such as AgCO3. Will the porous substance with the salt dissolved in it introduced a pyrolysis zone, the salt decomposes under CO2 gas release and the released metal ion can interact with the inert carrier become catalytically active in the pyrolysis zone. Silver is catalytic Combustion and hinders the formation of aromatics in the Pyrolysis zone, especially in the presence of carbon monoxide Gas like CO2.

Important CO2 release is the right time to introduce it of the material with the pyrolytic hindrance of formation Polycyclic aromatics.

An inert carrier delays the release of the materials and the thermal decomposition of the salts in advance via the radiant heat. The delay depends on the size and heat capacity of the porous carrier or the size of the metal salt carbonate granules. CO2 is directly available in the Langmuirzone of combustion in a minimum concentration via the pyrolytic release from the chemically bound CO2. The concentration of CO2 in the Langmuirzone is crucial for the mixing ratio of the carbon salt into the tobacco. see sketches:
This means that the particle sizes are not too small, which means that the radiant heat triggers an early evolution of CO2 by decomposing the material - but are so large that the particles are pulled into the pyrolysis cell via the pyrolysis shift over the long mullet, thereby via contact - And radiant heat aufmimt the required heat of decomposition, and the CO2 passes through the pyrolysis without the Langmuirzohne, where the CO2 unfolds its pollutant properties, thereby highly reactivated, and thereby forms a solvent power for aromatics, when it with the negative pressure of the flow in the get colder tobacco tails. The particles may not be too large, they do not decompose when passing through the pyrolysis without

sketch 1 draws calcium carbonate granules, which are in front of the Langmuirzone no decomposition properties due to the size of the particles demonstrate. Migrate the Langmuirzone due to the burnup on the Carbonate particles, they migrate into the Langmuirzone and begin to thermally decompose and settle within this zone the process gas CO2 free, (sketch 2).

The Process gas CO2 forms a gas buffer and dissolves the aromatics from the base area before the Langmuirzone out, the aromatics be dissolved in the gas stream. Upon decomposition of the carbonate salt arise also metal oxides, the catalytically active within the combustion zone become.

sketch Figure 3 shows the ashing of the carbonate salts to metal oxide.

The Simple dissolution of the salts in the tobacco reduces the contact-catalytic Effect of gas and metal ion on the pyrolytic barrier effect the emergence of polycyclic aromatics.

Of the Carrier for the material with the pyrolytic Disabling effect of the formation of polycyclic aromatics is a inert highly porous material with deposited metal like silver. By way of example wet-chemical or vapor-deposited, metallic Silver as a coating, in particular partial coating on face silicate particles, in particular swellable phyllosilicate particles in Essentially from a mineral of the smectite group, such as. Bentonite, Montmorillonite, hectorite, saponite, beidellite, sauconite etc., natural or of synthetic origin or of mixtures of these minerals. ceramic Particles such as zeolites, hydroxyapatite, zirconium phosphates and others Metal-ion-exchanging ceramic materials, in particular the Hydroxyapatite particles are also successfully used.

described is applied to an inert highly porous material combustion catalytic metal such as silver. Exemplary wet-chemical or evaporated, metallic silver as a coating, in particular Partial coating on zeolite. It can also be a silver particle, especially silver nanoparticles with extremely high surface area Act as it did in mesoscopic production Metal networks with large internal surfaces in the "prior art" is described, and based on the reduction of (noble) metals in supramolecular organogels, for example, in-situ formed metallic nanoparticles adsorb on the surfaces of gel fibers and can potentially grow together to form closed metal networks.

Becomes the porous substance with the salt dissolved in it introduced into a pyrolysis zone, the salt decomposes under CO2 gas release and the liberated metal ion may interact with the inert carrier and the metal surface applied to it in the pyrolysis zone become catalytically active.

Silver, also in particular in connection with ionic calcium is catalytic Combustion and hinders the formation of aromatics in the Pyrolysis zone, especially in the presence of carbon monoxide Gas like CO2. Subsequently, this substance is called KATALYTSUBSTANZ designated.

At the Dissolve carbonic acid salts in the organic Material itself, pyrolyzes the organic material and the salt decomposes thermally under CO2 gas release, which of mostly From the outside approach the Langmuirzone and enter it to electrochemically interact with it to get the desired effects to reach.

there it comes to a combination of together over the overlay effect interacting pyrolysis-influencing processes.

Within a pyrolysis-burning organic base such as tobacco is the Application ideally suited.

The Amount of smokable material with catalytic substance inside the tobacco rod or tobacco strand may vary. Packing densities for Tobacco stubs of cigarettes are typically between about 150 and about 300 mg / cm 3, and preferably between about 200 and about 280 mg / cm3, but may be higher or lower Quantities preferred for certain embodiments be.

typically, A tipping material surrounds the filter element and an adjacent one Area of the smokable rod or strand, so that the tpping material about 3 mm to about 6 mm along the length of the smokable Stabs extends. Typically, the tpping material is a conventional one Paper tipping material. The tpping material can essentially be impermeable to air, permeable to air or by mechanical means or other perforation procedures should be treated as having one Area of perforations, opening or vents whereby a means is provided for air dilution to provide for the cigarette. The total surface the perforations and the positioning of the perforations along the scope of the cigarette are capable of variation to the characteristic To control the performance characteristics of the cigarette.

For example can be used for a filter element with a length of 27 mm the maximum distance between about 23 mm and about 26 mm be from the extreme mouth end of the filter element. In a preferred aspect is the air-dilution device towards the extreme mouth-end of the cigar relative to the smoke-altering one Filter segment arranged. For example, for a Including filter element with a length of 27 mm a smoke changing filter segment of 12 mm and a 15 mm mouth-end segment a ring of air-dilution perforations either 13 mm or 15 mm from the extreme mouth end of the filter element be located away.

Of the Expression "air dilution", is the ratio (generally expressed as a percentage) of volume Air related by the Air Dilution Facility is, to the total volume of air and smoke, by the cigarette is pulled and at the extreme mouth-end section the cigarette comes out. For air-diluted or equipped with a ventilation device cigarettes can the Amount of air dilution vary.

Generally is the amount of air dilution for an air diluted Cigarette greater than about 10%, typically greater than about 20% and often larger than about 30%. Typically, with relatively small cigarettes Circumference (for example, about 21 mm or less) of the air dilution be slightly lower than cigarettes with larger ones Scope. The upper limit of the air dilution for a cigarette is typically less than about 85% and still more often less than about 75%. Certain relatively high-air-diluted Cigarettes have air dilution levels of about 50 to about 75%, often about 55 to about 70%.

cigarettes certain embodiments may be less than about 0.9, often less than about 0.5 and usually between about 0.05 and about 0.3 FTC "tar" per turn on average when smoked under FTC smoke conditions (FTC smoke conditions include a volume of 35 ml traits of 2 seconds. Duration, separated from about 58 s of glow).

cigarettes with "ultra-low tar content" are those Cigarettes containing less than about 7 mg FTC "tar" per Cigarette. Typically, such cigarettes yield less as about 9 moves, and often about 6 to about 8 moves, when smoked under FTC smoke conditions. While are Cigarettes with "ultra-low tar content" in general preferred, however, come in certain embodiments Cigarettes less than about 0.05 or more than about 0.9 FTC "tar" per turn result.

In certain embodiments, cigarettes are provided a low or negligible amount of nicotine result. Such cigarettes generally give less than about 0.1, often less than about 0.05, often less than about 0.01 and even less than about 0.005 FTC nicotine per turn on average, when smoked under FTC smoke conditions. In other Embodiments may desire a cigarette which provides higher levels of nicotine. Cigarettes can deliver about 0.1, 0.2, 0.3 or more FTC nicotine per turn on average, when smoked under FTC smoke conditions.

cigarettes, a low or negligible amount of nicotine can result in between about 1 mg and about 20 mg and frequently about 2 mg to about 15 mg of FTC "tar" per cigarette yield and can be relatively high ratios FTC "tar" too FTC have nicotine, for example between about 20 and about 150. Cigarettes of the preferred embodiments may show a desirably high resistance to train, For example, a pressure drop of between about 50 and about 200 mm water pressure at 17.5 cc / s air flow.

cigarettes preferred embodiments may include the smoke include changing filter segment with catalytic substance. The smoke-changing filter segment can be the content on one or more undesirable components in the smoke reduce and / or increase the tobacco smoke flavor, a richer smoke character, an improved feel in the mouth and provide increased satisfaction with smoking, as well as an improvement of the perceived characteristic traction properties the cigarette.

In In a preferred embodiment, smoke objects, include the catalytic substance or only the metal carbonates, Also, a catalyst system, the catalytic metal and / or includes porous carbon particles. The catalyst system is incorporated into the smokable material so that it's the concentration at certain unwanted components in the resulting Smoke reduced.

alternative the metal particles can include particles, which include a core of a carrier material, the essentially of a layer of catalytically active metal or metal oxides.

Where the salt is under CO2 gas release decomposes and flavors from the pyrolizing carrier material release and burn the tobacco filling as well as the Heat generated by the burning of the tobacco filling is, the compound pyrolyzed. What the released metal ion with the inert support and the metal surface applied to it becomes catalytically active in the pyrolysis zone. It applies again, the the particle sizes are not too small are that the radiant heat is an early one CO2 evolution by decomposing the material but the particles are so long over the Langmuirzohne into the pyrolysis zone, thereby and radiant heat the required heat of decomposition and the CO2 over the pyrolysiszohne to Langmuirzohne where the CO2 reduces its pollutants Characteristics unfolds while reactivating highly, and doing so Solvent capacity for aromatics is formed. The particles should not be too big that they did not decompose on passing through the pyrolysis.

In preferred embodiments are methods and preparations for releasing CO2 into the ranch stream to release aromas a smoke object into the smoke flow into it, for example provided with a cigarette, but below temperatures, in the tobacco rod at a distance of 1 cm or more from the combustion cone can be achieved in a burning cigarette. additionally to decompose to form CO2, the compounds have as additional Decomposition by-products chemicals that are judged so that they do not pose a significant risk to the smoker. The decomposition by-products in conjunction with those by the CO2 dissolved aromas also do not adversely affect the taste of the cigarette.

The preferred embodiments relate to smoking articles such as cigarettes, cigars and pipe tobacco and affect in particular cigarettes, which have a reduced content of different polyaromatic hydrocarbons (polyaromatic hydrocarbons; PAHs), tobacco-specific nitrosamines (tobacw specific nitrosamines; TSNAs), phenolic compounds and certain other undesirable components in cigarette smoke, resulting in both mainstream smoke as well also includes side stream smoke, or cigarettes, which have a reduced content of TSNAs, nicotine or other undesirable ones Have components in the unburned smoke product.

permanent Gases (such as carbon dioxide) account for 80% of the smoke and are generally undisturbed by filtration or Adsorption materials. The concentrations of organic volatile components, semi-volatile components and nonvolatile Components can be reduced by filters of different construction become.

The filter may include one or more material (s) of the catalytic substance or a metal carbonate which are capable of catalyzing, catalytically binding, adsorbing or reacting with at least one undesirable component of tobacco smoke. The carbon salt releases CO2 in contact with gas smoke and decomposes with oxygen to form a metal oxide, which basically reacts further with the resulting water and flue gases.

Of the Adsorptive effect associated with layered minerals, especially with metal coating and carbon salt content is mainly one physical effect. Smoke compounds diffuse in layered mineral filters in the organic volatile or semi-volatile Phases through the carbon particles. They move over the surface and then move into the pores of the layer minerals, and caused by a phenomenon known as "van der Waals forces" is. Although these forces generally considered weak They are strong in the very short range (one or two molecule diameters) enough to attract and retain smoke components.

Verification and clarification of inventor height over demonstration trials (to inventor height particle size of the additive METAL Corbonate)

We offer the cigarette industry the opportunity of using minerals as additives in cigarette tobacco the pollutants (hydrocarbons and toxic gases) by up to 50% in cigarette smoke when smoking one To reduce cigarette with the subjective taste impression of original cigarette.

The reduced harmful pollutants at a glance:

In summary we can say that when using 16% wt. shares C4_0 mineral and health hazards Lower substances in tobacco smoke between 35% -50% without the taste and the feeling of the original To change the cigarette.

It but are by far even greater subsidence possible!

examination and report on the following pages.

Aim of the investigation:

aim The investigation is to find an additive that is the most important harmful substances when smoking a Cigarette arise to degrade without the taste, flavor and to significantly reduce nicotine levels.

in this connection Great attention was paid to the cigarette from smoking feels like a normal cigarette without the typical "LIGHT" effect.

We try to stay close to the maxim "A cigarette Must be fun to smoke "

Us is aware that we are capable of making a quantitative statement with regard to the effect in the concentration used to reach. To make qualitative and accurate statements needed one the technical possibilities, as only a cigarette manufacturer Has.

For this are then measurements of tobacco smoke in mass spectroscopy necessary with a precise and guaranteed distribution of ours Substances within the tobacco.

We provide with the investigation a quantitative statement, based Based on comparative measurements of the original tobacco to our with Additives added tobacco.

substances to be damped:

in this connection in particular hydrocarbons are meant that are suspected even in the smallest amounts of human cells cause cancer (Benzenes, toluene, phenol).

But it should also be curbed hydrocyanic acid and CO. substance Summary Benzene / benzene Benzene / benzene is the simplest and at the same time classic example of aromatic hydrocarbons. The molecular formula is C6H6. Benzene / benzene is highly carcinogenic toluene Toluene, common name according to IUPAC also toluene, methylbenzene, phenylmethane, called methylbenzene according to IUPAC nomenclature, is a colorless, characteristically smelling, volatile liquid, which resembles benzene in many of its properties. Toluene is an aromatic hydrocarbon phenol Phenol is hydroxy-substituted benzene and has the molecular formula C6H6O. He belongs to the group of aromatic hydrocarbons CO Carbon monoxide is a colorless, odorless and tasteless poisonous gas. cyanide Hydrogen cyanide (hydrocyanic acid), the nitrile of formic acid, is a colorless to slightly yellowish, flammable and water-soluble liquid with a characteristic, unpleasant odor of bitter almonds. Hydrocyanic acid and all cyanides are very toxic

Use of minerals

It Here comes a mineral used that by pyrolysis in the Langmuirzone is able to form a highly reactive CO2 gas. On the one hand, a mineral is used, which is used during pyrolysis Pyrolytically reactivated CO2 gas dissolved out of the organic material and thus the pyrolysis lowers temperatures, at the same time a improved solution of aromatics before and during the pyrolysis is initiated.

The Relationship between simple ineffective combustion and Deflagration of the mineral and CO2 gas will be greatly affected by the particle size dependent on the mineral.

The here most effectively shown mineral in the composition and the particle size can be on the free Market in DE for about 75,00-100,00 Euro per 1,000 kg - depending on the purchase quantity.

Of further, the tobacco may additionally contain an absorbent sheet silicate mineral be added to create an absorbing effect.

By the use of the molecular sieve becomes an overall attenuation reached. The greater the damping all the more bigger also the Lighteffekt in the cigarette smoke. Due to the reactive effect of the CO2 gas in the Langmuirzone be the stored toxic elements are no longer released.

in this connection consider the effect and the taste of the cigarette.

Subject to the taste and smokeability of a cigarette - "fun on Smoking "can be said to be here in second place mentioned layer silicate mineral is not absolutely necessary to dampen the toxic substances in the cigarette smoke, since In this case also the aromas are partially absorbed.

To the Weighed the minerals and tobacco came two different scales for use.

To In our first measurements we had to find out that everything was in order the flue gas came in contact, all substances more or less were absorbed. For this we had to develop a procedure always reproducing results.

• 1. Membranpumpen komplett reinigen (alle zehn Messzyklen die Membranpumpen komplett reinigen)
• 2. vor dem ersten Messzyklus eine Charge an Zigaretten verrauchen (verhindert bei der ersten Messung eine uneinheitliche Absorption durch die Membranpumpen. Damit wird für die nächsten 10 Messzyklen eine einheitliche Absorption durch die Membranpumpen gewährleistet)
• 3. Das Einrauchen geschieht im seperatem Raum gegenüber dem Messraum (verhindert eine Kontaminierung des Mess raumes mit Tabakrauch)
• 4. bevor die Zigaretten eingeraucht werden um das Rauchgas spektrometrisch zu messen, wird die Gaszelle mit Raumluft 45 Sekunden durch eine Pumpe gespült

To ensure reproducible equality, the following procedure and procedure were chosen:

• 1. Clean the diaphragm pumps completely (clean the diaphragm pumps completely every ten measuring cycles)
• 2. consume a batch of cigarettes before the first measuring cycle (prevents uneven absorption by the membrane pumps during the first measurement, ensuring uniform absorption by the membrane pumps for the next 10 measuring cycles)
• 3. Smoking takes place in a separate room opposite the measuring room (prevents contamination of the measuring room with tobacco smoke)
• 4. Before the cigarettes are smoked to measure the flue gas spectrometrically, the gas cell is flushed with room air for 45 seconds by a pump
• 5. after a minute we recorded the IR background noise and saved it as a background (15 IR measurement cycles)
• 6. Go to the smoking room for approx. 20 seconds, light cigarettes, connect the hose as a flue and in 4.5 minutes use 6 cigarettes in parallel with 10 moves a 1.8 seconds through the diaphragm pumps and catch the flue gas in the frying tube (the whole process takes approx 5.5 minutes - 5 minutes 30 seconds)
• 7. about 20 seconds to go back to the measuring room with the flue gas. Connect the flue gas hose to the measuring cell.
• 8. By pressing on the frying tube, a uniform flow of flue gas through the measuring cell is initiated and ensured. Initiate IR measurement cycle (15 IR measurement cycles for a curve determination). After completion of the measurement, rinse the measuring cell with fresh air for approx. 45 seconds using an electric pump.
• 9. Save the trace.
• 10. next consumption and measurement cycle (continue with point 4)

Experiments and analyzes

introduction

Gas flow guided within a flow reactor, which passes around the pyrolysis and its surrounding Langmuirzone, it means in a pyrolysis of organic material with aromatics, the Aromatic constituents of the organic material by the presence of CO2 (due to the admixture of certain minerals in the tobacco) before the pyrolytic zone and during the pyrolytic process by the pyrolytically reactivated CO2 gas dissolved out of the organic material, and taken with the gas stream. Also inhibits the formation of polycyclic aromatics such as benzene, toluene, phenol and the toxic gas CO and hydrocyanic acid.

Description of the experiments

As mentioned above, we want a quantitative reduction the pollutants by IR spectroscopy. We can only a percentage reduction with constant taste compared to the Show original. The qualitative determination of the reduction must the cigarette manufacturers themselves perform as we the Do not possess experience and taste in tobacco.

For the final provision and statements were about 95 series of measurements carried out.

Result is a maximum attenuation of unwanted substances with the same taste and sense of strength as the the original cigarette.

It are even greater attenuation of the unwanted Pollutants possible, with the taste and the sensation of strength compared to the original cigarette in the subjective taste sensation lose weight.

For this the cigarette maker has to do his own tests and determine how far the pollutants are lowered even further should!

In Of course, the test series were also subjective Smoke and taste impressions with natural Persons made (see smoke and taste impressions)

If the areas are spread on, it can be said that the hydrocarbons (benzene / benzene, toluene and phenols) in their Values can be lowered by 45%. CO is reduced by about 35% -40% and the attenuation of hydrocyanic acid should be around 50%. More accurate mass results only via a smoking machine and GCMS determination.

in the Result, it is easy to see that the CO2 values of all Subjects are of the same order of magnitude. Thus one can conclude that the combustion is in the same Magnitude is only with fewer pollutants. Similar the principle of exhaust gas recirculation, as is the case with the Automobile manufacturers is used.

To the One is a mineral used, the pyrolysis a pyrolytic Reactivated CO2 gas extracted from the organic material and thus the pyrolysis lowers temperatures, at the same time a improved solution of aromatics before and during pyrolysis is initiated (see red curve). Second Here comes, as known from laboratory technology, a molecular sieve Use (natural mineral). Through the molecular sieve the pollutants and flavors in front of the pyrolysis zone become part of it captured and saved. During the pyrolysis the substances are released again, but by the obstruction of the CO2 gases, the pollutants are largely retained the aromatics for the most part in the gas stream be released.

The Damping of the pollutants is metrologically not quite so good as when using twice the amount of mineral that at pyrolysis a pyrolytically reactivated CO2 gas from the organic Material dissolved out and thus the pyrolysis temperatures lowers and hinders the formation of harmful gases. To the others cut the taste impressions of the smoky ones Cigarettes by test persons (see smoke and taste impressions) in the result worse off.

The Figure 9 shows the minerals (16% by weight of the total weight), which hinder the formation of pollutants by a reactive CO2 gas. The minerals differ greatly in their mean Particle diameter.

Only the red trace has a slightly different mineral composition (10%).

• • rote Messkurve: mittlerer Teilchendurchmesser 110 μm
• • lila Messkurve: mittlerer Teilchendurchmesser 70 μm
• • grüne Messkurve: mittlerer Teilchendurchmesser 35 μm
• • blaue Messkurve mittlerer Teilchendurchmesser 20 μm

Picture nine shows the original tobacco smoke in the black trace like the pictures in front of it.

• • red trace: average particle diameter 110 μm
• • purple trace: average particle diameter 70 μm
• • green trace: mean particle diameter 35 μm
• • blue measurement curve average particle diameter 20 μm

If we attenuate the pollutants over the look at the red characteristic, the differences are not too far apart (max 20% less damping at the same Use of materials of the various additives). It is here, however very large differences of subjective taste and Strength sensation while smoking different cigarettes before (tested in 3 subjects, averaging 15-25 cigarettes smoke per day).

There we do not study all combinations of mixture variants There is still great potential here for the taste with the desired attenuation of pollutants (greater as in our investigation).

Smoke and taste impressions

It are each 6 different cigarettes Regardless of a total of 3 subjects tasted.

The Subjects smoke between 15-25 cigarettes each Day.

When Original tobacco was used by REEMTSMA West Red.

Below is a summary of the subjective tastes of the subjects. description Description of the impressions West red 1 person: strongly perfumed ZC2_0 (green curve Fig. 8) Additives of two components (see Fig. 8) all 3 people: is weaker than the original (light taste). Has slight taste loss compared to the original FN10 (blue curve Figure 9) average particle diameter 20 μm all 3 people: is lighter than the original (easiest of all) taste / aroma toned 1 person: strong light taste MV240 (green curve Fig. 9) average particle diameter 35 μm all 3 people: is lighter than the original. (is in the middle Taste is pronounced one person: on the tongue enhanced taste (unnatural to the original) FW270 (purple curve Figure 9) average particle diameter 70 μm all 3 people: is a little lighter than original in taste like the original C4_0 (red curve Figure 6-9) mean particle diameter 110 μm and 10% other mineral composition 2 people: is as strong as the original 1 person: is a little (barely perceptible) stronger than the original 3 people: taste the same as the original

Summary of test results:

In summary can be said that with a use of 16% wt. shares C4_0 mineral and health hazards Lower substances in tobacco smoke between 35% -50% without the Taste and change the feel of the cigarette.

The different combinations of minerals in particle size and composition can certainly achieve even better results. Especially in view of the cigarette industry has other ways to ensure distribution within the tobacco. Especially then, if you allow the cigarette to taste more of a light cigarette.
