Title: Improvements in or relating to activated alumina products
IPC: B01J20/08
Filed: 1963-04-16
Abstract: Alumina granules, uniformly impregnated with an alkali metal permanganate, are produced by calcining alumina trihydrate to form a calcined alumina capable of at least partial rehydration, mixing the calcined alumina with an alkali metal permanganate and water, granulating the mixture and partially rehydrating the granules. Calcination may be carried out at 500-800 DEG  C. for a time ranging from less than one second to ten seconds.  The permanganate concentration of the impregnated granules may be 2-4% on a dry basis. Granulation may be affected by any suitable method, e.g. extrusion, briquetting or tumbling, and impregnation with permanganate may be carried out either prior to or during the granulation. The impregnated granules may be rolled prior to being dried.  In a typical example, alumina trihydrate is calcined by injection through a gas flame, and ground to a size such that 69.3% is less than 325 mesh (Tyler).  Aqueous potassium permanganate solution is prayed on the alumina in a tumbling mill. The impregnated alumina is partially rehydrated, by heating at 95 DEG  C. for 8 hoursALSO:Catalytically-active alumina granules, uniformly impregnated with an alkali metal permanganate, are produced by calcining alumina trihydrate to form a calcined alumina capable of at least partial rehydration, mixing the calcined alumina with an alkali metal permanganate and water, granulating the mixture and partially rehydrating the granules.
