Effect of activated carbon on cigarette smoke

Then, comprehensively examines the activated carbon pore structure of mainstream smoke particles with phase content in the conventional chemical composition is the relationship between the filtration efficiency, found that adding activated carbon can be reduced in different degrees in cigarette mainstream smoke conventional component content, and under the condition of the same dosage of activated carbon, the ternary composite way of flue gas composition of conventional filtration efficiency higher than binary compound mode. In the process of adsorption of flue gas components, the specific surface area of activated carbon with different pore structures determines its total adsorption capacity, and the pore size distribution affects its adsorption selectivity. The contents of total particulate matter, nicotine, moisture and tar in the mainstream smoke of cigarettes all increased stably with the increase of the number of suction outlets. In the process of cigarette smoking, the filtration efficiency of activated carbon with different pore structure to the conventional components of smoke changed dynamically with the increase of the number of suction ports. Qualitative description method was used to evaluate the sensory quality of activated carbon cigarettes. It was found that the addition of activated carbon increased the smoke suction resistance, reduced the smoke concentration and aroma, reduced the irritation, and had no obvious peculiar smell and discomfort, and had no negative effect on the sensory quality of cigarettes.  pellet activated carbon Combined with unique flue gas generator and gas circuit switching and high rate of dilution technology, established a new type of impact based on the online detection of cigarette smoke aerosol particle size distribution of test method and the device, when implemented by suction mouth fresh smoke aerosol particle size size, concentration and distribution state of real-time detection, to evaluate the new additives, Cigarette auxiliary materials provide a new method for analyzing the effects of aerosol particles in smoke. After observing the stability of the device and the repeatability of the method, the aerosol particle size distribution characteristics of several activated carbon cigarette smoke were detected by using this method. It was found that the addition of activated carbon could effectively reduce the particulate matter content in the mainstream cigarette smoke, but had little effect on the particulate matter distribution state. The specific surface area and pore size distribution of activated carbon have a certain influence on the number concentration of aerosol particles. The higher the specific surface area, the stronger the adsorption capacity, and the less the number of particles. When the specific surface area is similar, the pore size distribution has an important effect, and the activated carbon with larger pore content is more favorable for the filtration of flue gas particles. The particle number concentration of seven samples of flue gas aerosol particles above 99% was concentrated in the range of 0.007~ 0.948um particle size, and the mass concentration was concentrated in the range of 0.262~ 9.910um particle size. Both particle number concentration and mass concentration showed an upward trend with the number of suction ports. The average particle number concentration of mainstream flue gas aerosol was 6.46×108~8.86×10° /cm' per puff, and the average mass concentration was 3.13×10+~ 3.85×10' mg/m' per puff. The total particle number concentration in a single cigarette was 3.88×109~5.31×10° /cm3. The total mass concentration ranged from 1.88×105 to 2.31×105mg/m3. activated carbon manufacturers in china
