FIELD : chemistry. SUBSTANCE : invention refers to the method of catalyst preparation for the oxidation of the gaseous and vapourous hydrocarbons and for catalytic selective reduction DeNox. The method of catalyst preparation for the oxidation of the gaseous and vapourous hydrocarbons and for catalytic selective reduction DeNox includes formation of the catalytically active substance in the form of crystalline coating obtained by the way of the multistage crystallisation process carried out on the carrying bodies. The initial products for said catalytically active substance are rare earths and heavy metals (cobalt and/or manganese) compounds; the latter are salts soluble in the water and oxalic acid. EFFECT : increase of the catalyst life cycle. 8 cl
