Granular activated carbon is heated twice-the first carbonization and the second activation. The product is a granular activated carbon made of coconut shell, fruit shell and anthracite. After deep processing, the product has the characteristics of large specific surface area, developed pores, high strength, strong adsorption capacity, low ash content and low moisture.

Granular activated carbon is widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generators, air separation equipment, paint spray workshops, fish tank water purification and other fields as adsorbent materials and catalyst carriers.
