CATALYST AND METHOD FOR COATING A CATALYST CARRIER CONTAINING TWO DIFFERENT PARTIAL STRUCTURES WITH A CATALYTICALLY ACTIVE COATING

摘要

The invention relates to a method for coating a catalyst carrier with a catalytically active coating by means of a coating dispersion, said catalyst carrier containing at least two partial structures which differ in terms of the capacity thereof for absorbing the coating dispersion. The inventive method is characterised in that the absorbency of each partial structure is changed by pre-coating the catalyst carrier with a burnt off material or a liquid, and the catalytic coating is then applied to the filter body, dried and/or calcinated in a known manner.
