The coal based columar activated carbon selection of high quality anthracite coal as the raw material, it is firstly crushed into powder, mixed with coal tar and water, and then pressed into the column type and processed by natural drying of 24h. With 600 degree carbonization and 950 degree activation to form the final product.
Surface impregnation chemically modifies activated carbon through a fine distribution of chemicals and metal particles on the internal surfaces of its pores. This greatly enhances the carbon’s adsorptive capacity through a synergism between the chemicals and the carbon. And provides a cost-effective way to remove impurities from gas streams which would otherwise not be possible.
