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 characterised 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.
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, where the absorptivity of at least one partial structure is modified by precoating of the catalyst support and the catalytic coat is then applied.
Catalyst containing a catalyst support and a catalytically active coat applied thereon, the catalyst support having at least two partial structures, of which a first partial structure has a high porosity and a second partial structure a low porosity, and the catalytically active coat being present with a total mass on the catalyst support, where not more than 80% of the total mass of the coat are present on the partial structure having the high porosity.
