ABSTRACT:
A process for preparing an improved cobalt oxide catalyst for ammonia oxidation comprising decomposing a cobalt compound such as basic cobalt carbonate by heating to form cobalt oxide, then saturating the cobalt oxide with cobalt nitrate solution and reheating to give an active, durable cobalt oxide catalyst. In ammonia oxidation processes, the durable catalyst of this invention has a long catalyst life and gives improved conversion of ammonia to nitric oxide. Additionally, the catalyst of this invention is capable of performing at higher operating rates than known catalysts. Optimum yields are obtained when the catalyst is prepared from compounds derived from electrolytic grade cobalt.
