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 devi ce for carrying out this method and the use thereof.

Abstract: A copper-containing catalyst of the composition of N2O contains a compound of the formula MxAl2O4, where M is Cu or a mixture of Cu and Zn and/or Mg and x is from 0.8 to 1.5. The novel catalyst is used in a process for the catalytic decomposition of pure N2O or N2O contained in gas mixtures, at elevated temperatures.

Abstract: The invention relates to a catalyst which contains copper and which is provided for decomposing N2O. The inventive catalyst contains a compound of general formula M x Al2O4, in which M represents Cu or mixture s of Cu with Zn and/or Mg, wherein x has a value ranging from 0.8 to 1.5. The invention also relates to a method in which the inventi ve catalyst is used in order to catalytically decompose N2O which is pure or which is contained in a gas mixture at an increased temperature.
