ACTIVATED FIBROUS CARBON

摘要

A process for producing activated fibrous carbon comprises carbonizing and activating vegetable fibers in the presence of at least a member selected from the group consisting of ammonium salts of inorganic acids, nitric acid and boric acid as well as zinc chloride of about 5 to 80 parts by weight against 100 parts by weight of the vegetable fibers. The process increases remarkably a yield for activated fibrous carbon and therefore permits the supply of activated fibrous carbon at by far reduced costs as compared with the conventional process, and the resulting activated carbon shows the superior adsorption capability and flexibility.
