Abstract
A process for removing nitrogen protoxide from gas mixtures which 5 contain it, comprising contacting with a catalyst which contains mixed oxides of copper, manganese and rare earth metals in an amount expressed as percentage by weight of CuO, MnO and rare earth metal oxide in the lowest state of valency of 20-45% CuO, 50-60% MnO, and 5-20% rare earth metal oxide.
