Abstract
A process for the preparation of a supported catalyst containing a catalytically active metal such as a noble metal is disclosed wherein the supported catalyst is prepared by initially contacting the inert support with a base and disposing an amount of base in the support corresponding to 0.01 to 50 gram equivalents of base per gram equivalent of catalytically active metal to be deposited thereon, drying the so-treated support to a residual moisture content of less than 10 percent of the maximum absorbency of the support and thereafter impregnating the same with a salt solution of a catalytically active metal, e.g., a salt of a catalytically active noble metal. The inert support is one having a BET surface area of less than 20 square meters per gram. The catalyst is useful in hydrogenation, dehydrogenation, hydrogenolysis, oxidation, polymerization, isomerization or cyclization reactions.
