Title:
PROCESS FOR PRODUCING FIBROUS ACTIVE CARBON
Document Type and Number:
WIPO Patent Application WO/1984/001566
Kind Code:
A1
Abstract:
A process for producing fibrous active carbon, which comprises carbonizing and activating vegetable fiber in the presence of at least one member selected from the group consisting of inorganic acid ammonium salts, nitric acid, and boric acid, and about 5 - 80 parts by weight of zinc chloride per 100 parts by weight of the vegetable fiber. This process enables a remarkable increase in the yield of fibrous active carbon to such an extent that fibrous active carbon can be supplied with much less cost than with the conventional processes. The obtained active carbon is excellent in both adsorbing ability and pliability.
