Abstract
A reactor for the catalytic oxidation of ammonia to form nitrogen oxides which has a noble metal gauze catalyst and a heat exchanger in that order in the direction of flow, a catalyst for the decomposition of N O is located between the noble metal gauze catalyst and the heat exchanger and in a process for the catalytic decomposition of N O in a gas mixture obtained in the preparation of nitric acid by catalytic oxidation of ammonia, where the N O is decomposed catalytically over a catalyst of the decomposition of N O, the hot gas mixture obtained from the catalytic oxidation of ammonia is brought to contact with the catalyst for the decomposition of N O prior to subsequent cooling.
