FIELD: oxidation catalysts. SUBSTANCE: copper-chromium powder is prepared by mixing chromium and copper compounds and thus prepared powder is mixed with aluminum hydroxide, after which shaping, drying, and calcination at 470-750 C are performed followed by treatment with reductive gas mixture at 150 to 300 C. Catalyst is fit to be applied in oxidation of Cr(VI) compound- free release gases. EFFECT: increased catalytic activity. 9 cl, 1 tbl
