Coal based cylindrical activated carbon, which raw material is strictly selected anthracite, is made by powdering, bonding, high pressure extruding, and other production technology processes. It is black cylindrical granuler, and is widely used in the application of air purification, sewage water treatment, desulfurization and denitrification, solvent recovery, nitrogen making machine, air separation plant, and so on.
By comparing the adsorption effect of activated carbon on volatile and organic compounds, the following conclusions are drawn
The adsorption of VOCs and extractable organics on activated carbon is quite different. The higher the molecular weight of VOCs, the better the adsorption effect, while the lower the molecular weight of extractable organics, the better the adsorption effect. This is mainly because the volatile organic compounds are mainly small polar organic compounds, while the extractable organic compounds are large polar organic compounds. Activated carbon itself can be regarded as a non-polar adsorbent, and its adsorption capacity for non-polar substances in water is greater than that for polar substances. Moreover, when the molecular size of adsorbate is in a certain proportion to that of activated carbon, it is most favorable for adsorption. For the molecules with smaller polarity, the larger the molecular weight is, the more favorable the adsorption is.
The main conclusions are as follows: the adsorption capacity of activated carbon for various organic compounds in water is very competitive, and the adsorption capacity is not only related to the molecular structure of organic compounds, but also related to the amount of organic compounds in water. At the same time, for volatile organic compounds and extractable organic compounds, the relationship between their adsorption capacity and molecular weight on activated carbon is opposite. With the increase of molecular weight, the adsorption performance of extractable organic compounds decreased, while the adsorption performance of volatile organic compounds increased
