  • Process for oxidation of ammonia
    Patent number: 3931391
    Abstract: Catalysts suitable for the oxidation of ammonia to nitrogen oxides which are suitable to produce nitric acid are prepared by doping cobalt oxide, preferably Co.sub.3 O.sub.4 with 0.1-10 atoms %, preferably 0.5-3 atom % of lithium. In a given case, there is added a mold assist agent to form tablets, spheres, extruded pressed strands or honeycombs. The product is calcined in air or an oxygen stream at 300.degree.-700.degree.C, preferably 400.degree.-600.degree.C and subsequently tempered at 700.degree.-900.degree.C in a reactive gas mixture of air and 8-10 vol. % ammonia to increase the form stability.
