Coal-based pellet activated carbon is currently the most widely used method for treating industrial waste gas, especially for benzene waste gas with outstanding adsorption function.granular activated carbon Moreover, the price of coal-based columnar activated carbon is relatively affordable, which can not only meet the requirements of environmental protection, but also can be reused with the regeneration technology of columnar activated carbon.



Studies have shown that using columnar activated carbon as the adsorption material, through the industrial combined process of columnar activated carbon and catalytic differentiation, the entire activated carbon purification system completes the closed cycle of purification and desorption process, and the process of operation will not cause secondary pollution.



If air is used as the carrier under the condition of real constant temperature and constant pressure, when the airflow reaches a certain speed, the adsorption capacity of activated carbon can reach 600mg/g, and in an equal environment, the higher the temperature, the greater the adsorption effect of activated carbon Well, the larger the amount of organic solvent exhaust gas to purify and adsorb.



Pellet activated carbon is a kind of porous carbon-containing material. It has a highly developed pore structure. It is the porous structure of activated carbon that provides it with a lot of surface area, which can fully touch the impurities in the gas, and then gives it the unique characteristics of activated carbon. The adsorption function can easily reach the intention of adsorbing impurities in the air, just like the magnetic force is the same, many molecules on the pore wall of activated carbon can generate strong gravitation, so as to reach the intention of adsorbing harmful impurities into the pores.
