A catalyst for oxidation of ammonia to nitrogen oxide, in the form of granules, based on oxides of the metals of the group iron, cobalt and nickel, with or without the addition of a promoter with a support based on oxygen-containing compounds of aluminum and method of producing them and more particularly, a) a catalyst for the oxidation of ammonia to nitrogen oxide, in the form of granules with a sintered, porous alumina carrier, formed at least on the outer periphery by an alumina spinel and with a film of catalytically active nickel and cobalt oxides, especially cobaltous-cobaltic oxide with or without an added promotor on the spinel layer, as well as the method of producing and using it. |
