Abstract: In the reactor for the catalytic oxidation of ammonia into nitrogen oxides, which in the direction of flow contains, in this order, a precious-metal gauze catalyst and a heat exchanger, a catalyst for the decomposition of N2O is positioned between the precious-metal gauze catalyst and the heat exchanger. According to said method for the catalytic decomposition of N2O in a gaseous mixture obtained during the production of nitric acid by catalytic oxidation of ammonia, on a catalyst intended for the decomposition of N2O, the hot gas mixture obtained as a result of the catalytic oxidation of ammonia is brought into contact with the catalyst used for the decomposition of N2O before being cooled.

Abstract: PCT No. PCT/EP96/03971 Sec. 371 Date Mar. 10, 1998 Sec. 102(e) Date Mar. 10, 1998 PCT Filed Sep. 10, 1996 PCT Pub. No. WO97/10042 PCT Pub. Date Mar. 20, 1997The invention relates to a process for removing nitrogen oxides from a gas stream containing same, which comprises passing the gas stream (A) through a stage for absorbing the nitrogen oxides other than N2O in an absorbent or reacting the nitrogen oxides other than N2O with an absorbent at a pressure of from 1,5 to 20 bar, and (B) through a stage for reducing the amount of N2O, preferably employing the pressure level of step A, and to apparatus therefor and the use thereof.
