Reduction of tobacco smoke components yield in commercial cigarette brands by addition of HUSY, NaY and Al-MCM-41 to the cigarette rod

Abstract

The effect of two zeolites, HUSY, NaY and a mesoporous synthesized Al-MCM-41 material on the smoke composition of ten commercial cigarettes brands has been studied. Cigarettes were prepared by mixing the tobacco with the three powdered materials, and the smoke obtained under the ISO conditions was analyzed. Up to 32 compounds were identified and quantified in the gas fraction and 80 in the total particulate matter (TPM) condensed in the cigarettes filters and in the traps located after the mouth end of the cigarettes. Al-MCM-41 is by far the best additive, providing the highest reductions of the yield for most compounds and brands analyzed. A positive correlation was observed among the TPM and nicotine yields with the reduction obtained in nicotine, CO, and most compounds with the three additives. The amount of ashes in additive free basis increases due to the coke deposited on the solids, especially with Al-MCM-41. Nicotine is reduced with Al-MCM-41 by an average of 34.4% for the brands studied (49.5% for the brand where the major reduction was obtained and 18.5 for the brand behaving the worst). CO is reduced by an average of 18.6% (ranging from 10.3 to 35.2% in the different brands).

TGA–FTIR study of the thermal and SBA-15-catalytic pyrolysis of potassium citrate under nitrogen and air atmospheres

“…Recently, the use of different porous structured solids has been studied to reduce the evolution of different compounds from tobacco smoke in order to reduce its toxicity [29,30], and the effect of these materials on the pyrolysis reactions of different tobacco additives has been studied using TG and TG-FTIR techniques [20,21]. The objective of the present paper is to study the thermal decomposition of potassium citrate by TG-FTIR and the effect of SBA-15 in such reactions both in N 2 and in air atmospheres, which to our knowledge has not been reported previously.…”

Effect of Time, Temperature and Stirring Rate Used in the First Step of the Synthesis of SBA-15 on Its Application as Reductor of Tars in Tobacco Smoke

“…However, there is a series of additives that produce a different effect to those previously described. During the last years, the use of catalysts as an additive in tobacco or in some of the elements that conform the cigarettes is being studied [14][15][16]. The presence of the catalysts in the combustion process of tobacco produces a significant effect in the reduction of the toxic compounds generated during the smoking process.…”

Effect of Reaction Time and Hydrothermal Treatment Time on the Textural Properties of SBA-15 Synthesized Using Sodium Silicate as a Silica Source and Its Efficiency for Reducing Tobacco Smoke Toxicity

“…Great research efforts have been focused on the addition of various materials on tobacco with the aim of reducing the number of toxic compounds in smoke. In this sense, some mesoporous materials have been studied as elements capable of retaining some of these compounds [28][29][30][31][32][33][34].…”
