A method of reducing the content of NO x and N 2 O in gases using a gaseous reducing agent which is used in the amount required for reduction of the NO x in the presence of one or more iron-laden zeolites which have no pores or channels having a width of greater than or equal to 7 Ångström in the crystal structure and at temperatures of less than 450° C. in the reaction zone is described. In this method, the flow rate of the gas mixture and/or the amount of catalyst is/are selected so that the desired degree of decomposition of N 2 O is achieved. The method can be used, in particular, in nitric acid production, in power stations and in gas turbines. |
