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.
Generally speaking, forming carbon can be mixed with a variety of raw coal to adjust the pore distribution characteristics of the final product, so as to obtain some special application performance, and more than 80% of the pore distribution characteristics of raw coal directly broken carbon has been determined by the raw material, so the performance and use is simple.coconut shell activated carbon suppliers
(2) wood activated carbon.It is mshell/core activated carbon.Such as coconut shell carbon, apricot kernel carbon, peach kernel carbon, etc.(4) petroleum activated carbon.Using petroleum asphalt, petroleum coke as raw materials, made of activated carbon products.resin activated carbon.Using phenolic resin, waste ion exchange resin as raw materials, through a special process of activity.Carbon products, sometimes fibrous carbon also falls into this category.High - definition watermark of cut document under air(6) other small varieties of activated carbon products.The experimental results show that the surface structure of the activated carbon material modified by FeSO changes: the specific surface area decreases, the surface oxygen content increases, the plane of the random layer graphite carbon net is destroyed to a certain extent, and the ammonia absorption capacity and benzene absorption performance of the sample are greatly enhanced.He ChunHong et al. [reported the research progress of supporting activated carbon materials in the removal of SO; the removal ability of SO was significantly enhanced after supporting Co, Ni, Mg, and V compounds, which was due to the formation of Co(OH)2, Ni(OH)2, Mg (OH)2, and V,0 microcrystals on the surface of activated carbon after supporting, which enhanced the desulfurization activity of activated carbon.coconut shell activated carbon suppliers
