Coal-based columnar activated carbon is made of high-quality anthracite and refined by advanced technology, and its appearance is black cylindrical particle. It has the characteristics of reasonable pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration and low cost. Used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery and other aspects.

Applicability of columnar activated carbon:

(1) Gas phase adsorption;

(2) Organic solvent recovery (benzene gas toluene, acetate fiber industry in acetone recovery);

(3) Remove impurities and harmful gases and recycle waste gas;

(4) Excessive gasoline recovery from refineries, gas stations and oil depots;

(5) It is used for the preparation of trichloroethylene by the removal of HCl with tetrachloroethane catalyzed by activated carbon
