The effect of the amount and adding method of activated carbon on smoke emission of cigarettes was investigated. It was found that the filtration efficiency of ternary compound filter was higher than that of binary compound filter under the influence of plasticizer when the amount of activated carbon was constant. With the increase of the amount of activated carbon, the filtration efficiency of the two kinds of composite filters increases. The effects of the amount of activated carbon on the filtration efficiency of the compounds with different volatiles are different. The effects of the amount of activated carbon on the filtration efficiency of the isomers are similar due to their close molecular weight and boiling point. When the dosage is small, the competitive adsorption is easy to occur. The adsorption amount of refractory components such as acetaldehyde is small, and the competition can be reduced by increasing the dosage. The filtration efficiency of refractory components shows an obvious upward trend with the increase of the dosage.coal activated carbon supplier
It was found that the contents of volatile compounds and flavor components were related to the type of cigarettes and the amount of tar. The contents of volatile compounds and flavor components were higher in the flue-cured cigarettes than in the mixed cigarettes, and higher in the high tar cigarettes than in the low tar cigarettes. The types of fragrance components in smoke of different types of cigarettes are basically the same, but there are great differences in content. The contents of furfural, furfuryl alcohol, maltol, 5-hydroxymethylfurfural, linolenic acid, methyl linolenic acid, linoleic acid, methyl palmitate and other components in flue-cured cigarettes were significantly higher than those in mixed cigarettes. This is related to the higher carbohydrate content in flue-cured cigarettes. Mixed-type cigarettes contain high content of 3-methylpentanoic acid and nitrogen heterocyclic compounds such as cotinine, ho ah, and methamine due to their formulations of burley tobacco and spice tobacco. The filtering law of activated carbon for different types of cigarettes is basically the same, that is, the filtering efficiency is related to the properties of compounds, especially with the molecular weight and boiling point of compounds. The filtration efficiency of activated carbon on flue-cured cigarettes was lower than that of mixed cigarettes.granular activated charcoal

High efficiency: super current discharge capacity, high energy conversion efficiency, small process loss, high current energy cycle efficiency ≥90%.At present, the organic pollution of drinking water source is relatively serious. The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation in the removal of organic matter, ozone catalytic oxidation technology can induce the formation of hydroxyl radical (·OH) with high oxidation ability, which can effectively remove trace organic pollutants in water and reduce the content of ozone oxidation by-products. Therefore, it is a drinking water treatment method with great application prospect.
Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics.granular activated charcoal
