METHOD OF PREPARING CATALYST FOR PURIFYING GAS TO REMOVE ORGANICS AND CARBON MONOXIDE Russian patent published in 1996 - IPC

FIELD: petroleum processing; chemical engineering; thermoelectricity. SUBSTANCE: catalyst suitable for use in sanitary thermocatalytic purification of low-pressure oxygen-containing gases to remove noxious admixtures (for example, leaving gases in process of catalyst and sorbent regeneration) is prepared by covering a non-porous carrier with catalytically active suspension. The latter consists of catalytically active component and binder component, which is saturated aqueous solution of alumina-chromophosphate binder, at their weight ratio (3-5):1, ratio of components in binder solution Al₂O₃:Cr₂O₃:P₂O₅ being 1:(1-0.5):(2-4). EFFECT: prolonged catalyst life due to elevated mechanical strength, thermal stability, and catalytic activity; eliminated environmental pollution when preparing catalyst. 5 cl, 4 tbl
