Research And Development Of Additives For Lower Yield Of Carbon Monoxide In Mainstream Smoke Of Cigarettes Of Yunnan Province

Carbon monoxide (CO), produced in a burning cigarette, is one of the main components of tobacco maimstream smoke, which have negative effect on human body. And this issue is always one of the key problems to tobacco scientists to reduce the yield from cigarette. However, it is every difficul to reduce CO with chemical technology because there was lack of fundamental research.This dissertation focuses on the reduction of CO emissions in cigarette mainstream of Yunnan tobacco industry, Based on the characteristics of cigarette products of HTG, which means that the cigarette was aroma adequacy and has a high rate of CO to Tar (general, CO delivery is2mg/cig higher than that of Tar), new technologies, such as cigarette paper additives, tobacco additives and other aspects for reducing deliveries of Tar and other harmful components, have to be studied and their applications in tobacco industry should also be tested.This study followed the comprehensive consideration of the principle, using factor analysis method, ratio method, comparative method and other techniques, drop in the tar, carbon monoxide (CO) and keep the quality of smoking the cigarette two seek balance point; the choice of38different brands of cigarettes,In order to reduce the delivery of CO in mainstream smoke, additives for shredded tobacco and cigarette paper, the burning regulator especially, were investigated systematicly. At the same time, in order to test the feasibility of industrialization, the additives were tested in pilot-plant and the experimental results showed that the tobacco and cigarette paper burning regulators meet the industry requirment and they can significantly reduce the delivry of CO of cigarettes.
