The catalyst renders harmless processed gases from internal combustion engines and for industrial waste gases. It has a high catalytical activity and mechanical strength, while its active phase is formed at relatively low temperatures. The catalyst contains in mass%: Co (III) oxide from 22 to 45, Cu (II) oxide from 10 to 20, BN from 0.1 to 3.5, Si (IV) oxide from 20 to 45, Al2O3 from 2.5 to 10, MgO from 2.5 to 10 and Fe (III) oxide from 0.4 to 2.
