ABSTRACT:
A process for the preparation of a metal-containing supported catalyst, having at least one metal or metal compound substantially present in a selected part thereof comprising contacting a aqueous solution of an appropriate metal compound with a reagent capable of changing the valency of said metal during contact with a preshaped support.
The resulting catalyst, which may have an egg-shell or an egg-yolk type distribution for the catalytically active component, may be used e.g. in diffusion limited processes as well as in processes wherein the feedstock may contain catalyst poisons, e.g. in residue conversion.
