Solvent recovery columnar activated carbon

Solvent recovery and treatment activated carbon is made of high-quality natural coal as raw material and refined by physical activation method. It is black granular, with well-developed pores, reasonable distribution of three types of pores, and strong adsorption capacity. It has more adsorption capacity for most organic solvent vapors in a wide concentration range, and is widely used in organic solvent recovery.

Coal-based columnar activated carbon is a black cylindrical particle processed by a series of advanced processes using selected high-quality raw coal or anthracite as raw materials. The columnar activated carbon processed by this complex process has a reasonable pore structure and high strength, so it has good adsorption performance and is widely used in the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery and so on. The coal-based columnar activated carbon itself has a well-developed pore structure, good adsorption performance, high mechanical strength, and the coal-based columnar activated carbon is easy to regenerate repeatedly, so that the coal-based columnar activated carbon cost is lower.
