Activated carbon is porous carbon material. Due to highly developed porous structure and huge specific surface area, it has very strong adsorption capacity, which is widely used in industrial production, agriculture environmental protection as catalyst or catalyst carrier.Impregnated activated carbon is made from selected activated carbon by impregnating with different impregnant.The resultant product incorporates activity, selectivity and stability, and provides good catalysis and all-purpose protection.All-purpose protection not only against toxic gases such as cyanides and arsenides, but also against harmful gases such as acid gases, ammonia and carbon monoxide can be visualized. Desiccants thus made can effectively absorb water vapor from gases. Wide use is also found in national defense, industrial hygiene and safety, environmental protection, etc.

To be used packing the fiter, protecting against all kinds of toxics.
