METHOD OF PRODUCING GRANULATED ACTIVE ALUMINIUM OXIDE HAVING BIDISPERSE POROUS STRUCTURE Russian patent published in 1994 - IPC

Abstract SU 1580759 A1

FIELD: chemical industry. SUBSTANCE: pure aluminium hydroxide and dry waste of proposed process (its quantity being 3-30 mass % , its size being 10-80 μm) are plasticized with the help of nitric acid. Then molding thus prepared mass is carried out in aqueous solution of ammonia. Granules of desired product are dried a and calcined. EFFECT: increases strength of granules, lows price of the process. 1 tbl
