Abstract: Disclosed is a silver-containing carrier catalyst for the decomposition of nitrous oxide present as the pure gas or in gas mixtures. The carrier catalyst includes an aluminium oxide carrier with a BET surface area of 26 to 350 m /g. Also disclosed is a method in which the carrier catalyst proposed is used for the selective catalytic decomposition of nitrous oxide present as the pure gas or in gas mixtures at elevated temperatures.

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.
