Abstract

The invention relates to the catalyst for gas purification from carbon oxide, hydrocarbons, nitrogen oxides, for example, the internal combustion engines exhaust gases, flue gases of boiler-houses and others plants.The summary of the invention consists in the fact, that the iron and aluminium compounds are introduced in the catalyst for the oxide-spinel on support structure formation by electrochemical dissolution of Fe-Al anode at its abrasive-mechanical activation with the rotative cathode and feeding of the water solution of the catalytic active metals compounds. The formed product is dried, granulated and exposed to the thermic treatment. As the solution for the compound of the catalytic active metals are used the washing waters of the galvano- chemical processes and as the Fe-Al anode material the mixture of pressed chip wastes is used.The technical result of the invention consists in the preparation of the active catalyst with a high- specific surface.
