Abstract
Nitric oxide is formed by the oxidation of ammonia. An ammonia containing gas is contacted with an oxidation catalyst comprising stainless steel in the presence of oxygen at a temperature between about 500.degree. C. and 1100.degree. C. in order to effect a reaction selectivity of at least 50%.
Claims1
The process for oxidizing ammonia to form nitric oxide which comprises passing a feed gas containing ammonia and oxygen at an oxygen to ammonia volume ratio larger than 0.5 in contact with a stainless steel catalyst comprising stainless steel-316 containing 23% chromium, 18% nickel, 2% molybdenum, 0.5% carbon, the balance iron at a temperature between about 500.degree. C. and 1000.degree. C. and recovering nitric oxide produced.
