摘要： A process for preparing a catalyst comprising a metallic catalytic agent on a particulate carrier is disclosed which provides improved uniformity of distribution and fineness of division with narrowness of particle size distribution of the metallic catalytic agent on the carrier. The carrier is impregnated with an aqueous solution of a salt of the metallic catalytic agent and of a source, on heating in aqueous solution, of hydroxyl ions. The impregnated carrier is heated without substantial loss by evaporation of the aqueous solution to precipitate the metal or the particles with uniformity of distribution and fineness of division with narrowness of particle size distribution. The metal is converted by conventional methods to the appropriate active, oxidized or reduced, state. The process is particularly significant with carriers, such as alumina and silica, that in alkaline media are liable to undergo structural charges.
