The catalyst is prepared in two steps. In the first step a porous carrier is impregnated at least once with an aqueous solution of a molybdenum compound and the water is evaporated; in the second step, the said carrier is impregnated at least once, at temperatures of between 20* and 100*C, with an aqueous nitric acid solution of iron, bismuth and optionally silver nitrates and optionally phosphoric acid; after the last impregnation, the carrier so treated is allowed to remain in contact with the said aqueous nitric acid solution for a period of between 5 and 24 hours, water and nitric acid are evaporated with continuous agitation of the carrier, and the carrier with the said salts adhered thereto is dried at temperatures of between 100* and 300*C, and annealed at temperatures of between 450* and 550*C.

Abstract: 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 particles of carrier are suspended by agitation in an aqueous solution of a salt of the metallic catalytic agent and of a source, on heating in aqueous solution, of hydroxyl ions. The suspension is heated in a sealed vessel above 100* C 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 procedures 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.
