摘要: A catalyst with a porous, ceramic support body having a porosity which is formed by pores in at least a part of the ceramic support body, and which furthermore has a catalytically active washcoat coating applied to the ceramic support body, which catalytically active washcoat coating having a layer thickness, comprises a permanent catalytically inactive impregnation comprising at least one catalytically inactive inorganic component, and wherein the permanent inactive impregnation has a layer thickness and is present at least partially between a surface of the porous ceramic support body and the catalytically active washcoat coating is present in the pores of the ceramic support body in a region with reduced porosity underneath the surface of the ceramic support body.

摘要: In order to specify a catalytic converter, especially SCR catalytic converter, with maximum catalytic activity, this catalytic converter has at least one catalytically active component and additionally at least one porous inorganic filler component having meso- or macroporosity. The organic porous filler component has a proportion of about 5 to 50% by weight. More particularly, a diatomaceous earth or a pillared clay material is used as the porous inorganic filler component.
