Abstract: The invention concerns a method of removing nitrogen oxides from a gas flow. The gas flow is guided: (A) through a stage in which the nitrogen oxides, apart from N2O, are absorbed in an absorption agent, or the nitrogen oxides, apart from N2O, are reacted with an absorption agent at a pressure of between 1.5 and 20 bar; and (B) through a stage for reducing the N2O content, preferably using the pressure level prevailing in step (A). The invention further concerns a device for carrying out this method and the use thereof.

Abstract: Catalysts are produced by combining M-Al2O4, in which M stands for an element of the I, VII and VIII secondary groups of the periodic table of elements, with tin, lead, an element of the II main or secondary group of the periodic table of elements, as an oxide or salt or in its elementary form, and by calcinating them at temperatures from 300 to 1300 .degree.C and pressures from 0.1 to 200 bars. Also disclosed is a process for producing these catalysts.
