METHOD FOR THE CATALYTIC DECOMPOSITION OF N2O |
摘要 |
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 N20 is positioned between the precious-metal gauze catalyst and the heat exchanger. According to said method for the catalytic decomposition of N20 in a gaseous mixture obtained during the production of nitric acid by catalytic oxidation of ammonia, on a catalyst intended for the decomposition of N20, 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 N20 before being cooled.
