Spherical activated carbon (SAC) is a type of activated carbon in spherical shape produced from asphalt. In addition to the excellent absorption capacity, its unique forming process by smelting makes the activated carbon quite different from the ordinary wood/coal-based spherical or grain activated carbon products that are formed by binding agents.
Application: Solvent recovery, sewage treatment, ultrapure water purification, air purification, filtering mesh in clean rooms in the semiconductor industry, in-car environment purification, catalyst carrier, refining of fine chemicals, chromatographic column carrier, etc.
