METHOD OF PREPARING CATALYST FOR FREEING GAS FROM ORGANICS AND CARBON MONOXIDE Russian patent published in 1999 - IPC

Abstract RU 2131772 C1

FIELD: gas treatment catalysts. SUBSTANCE: invention, in particular, relates to treating auto-car exhaust gases and gases emitted from spray-painting chambers and other production installations when emission gases contain toxic substances and carbon monoxide. Catalyst is prepared by coating, in dipping mode, surface of metal, glass cloth, or ceramics with suspension containing 18-20% CrO₃, 18-20% Cr₂O₃, 30-32% MnO₂ in demineralized water, followed by drying at temperature not exceeding 80 C for 4 hr and calcination at 300-400 C for at least 1 hr. EFFECT: simplified procedure and reduced cost. 2 cl, 2 tbl
