ABSTRACT:
A process for the preparation of a catalyst comprises abrading a solid metallic material selected from platinum, palladium, platinum-palladium alloys and mixtures thereof, in the presence of an aqueous alumina suspension to obtain a suspension which contains finely divided particles of the metallic material and the alumina uniformly dispersed throughout, applying the thus obtained suspension to a support, and then removing the water therefrom to obtain the desired catalyst.
