Coconut shell activated carbon for petrochemical industry has high purity and large specific surface area. It is made from imported coconut shell carbonized material activated by ultra-high temperature superheated steam. Some products are also made by hydrochloric acid pickling. This product has rich pores, mainly medium and micropores, which can enable the catalyst to be fully distributed and firmly loaded on the surface of the pores. Excellent mechanical strength results in extremely low friction loss. The pickling process or water washing process removes metal ions and soluble solids from the carbon to prevent impurities from affecting the final product.
