Introduction:
Coal-based activated carbon is generally black cylindrical or granular in shape. Cylindrical activated carbon, also known as columnar carbon, is generally prepared by kneading, extruding, and then carbonizing and activating the powdery raw material and the binder, or by extrusion with powdered activated carbon and a binder. Features:It has developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration and low cost. It is widely used for purification of toxic gases, waste gas treatment, purification of industrial and domestic water, and solvent recovery.
Application:
Coal-based activated carbon is widely used in the deep purification of drinking water, industrial water, waste water and gas, and has functions such as decolorization, purification, impurity removal, deodorization, odor removal, carrier, purification and recovery.
