Abstract
The invention relates to a process for the coating of a catalyst support with a catalytically active coat using a coating dispersion, the catalyst support containing at least two partial structures which differ in their absorptivity for the coating dispersion. The process is characterized in that the absorptivity of the partial structures is modified relative to one another by precoating of the catalyst support with a material which can be burnt out or with liquid, and the catalytic coat is then applied to the filter body in a known manner, dried and/or calcined.
