Catalyst, process for producing it and its use Catalysts for the decomposition of N2O into nitrogen and oxygen in the gas phase, which comprises a porous support composed of polycrystalline or vitreous inorganic material, a cerium oxide functional layer applied thereto and a layer of oxidic cobalt- containing material applied thereto are described. The catalysts can be used, in particular, as secondary or tertiary catalysts in nitric acid plants.
L'invention concerne des catalyseurs de décomposition de N2O en azote et en oxygène en phase gazeuse, comprenant un support poreux fait d'un matériau inorganique polycristallin ou hyalin, une couche fonctionnelle en oxyde de cérium déposée sur ledit support et une couche de matériau contenant du cobalt oxydique déposée sur ladite couche fonctionnelle. Ces catalyseurs s'utilisent notamment comme catalyseurs secondaires ou tertiaires dans des installations de production d'acide nitrique.
