Coal activated carbon adopts high-quality coal as raw material, experiencing a seizes of processes:carbonization → cooling → activation → washing. Its appearance generally is black columnar activated carbon, amorphous granular coal activated carbon-also known as broken charcoal. Columnar Activated Carbon, is also known as columnar carbon, which is generally by powder material and a binder by kneading, extrusion and then through carbonization and activation processes . You can also use powder activated carbon to make it by adding binder extrusion. It has developed pore structure, good adsorption properties, high mechanical strength, easy to repeatly regeneration, and low cost.
Columnar activated carbon can be applied into Air Purification, Water Treament, Desulfurization, sewage treatment and so on.
