Abstract

a. Catalyseurs de dénitration comportant un revêtement poreux et procédé pour les produire. b. On produit un catalyseur de dénitration comportant un revêtement poreux par immersion d'une base de catalyseur en métal poreux dans un bain de revêtement contenant de la silice, séchage de la base de catalyseur pour former un support comportant un revêtement de silice poreux, immersion du support dans une solution contenant un composant actif et séchage du support obtenu, pour fixer le composant actif sur le support. c. Purification des gaz d'échappement.at. Denitration catalysts having a porous coating and a method for producing them. b. A denitration catalyst having a porous coating is produced by immersing a porous metal catalyst base in a coating bath containing silica, drying the catalyst base to form a support having a porous silica coating, dipping the catalyst base. support in a solution containing an active component and drying of the resulting support, to fix the active component on the support. vs. Purification of exhaust gases.
