Zusammenfassung:CATALYST MANUFACTURE Catalysts are made which have a catalytically-active composite containing a catalytically-promoting metal component and a high surface area, refractory oxide support, deposited on a macrosize carrier. The catalytically-active composite is made by combining a solution of a water-soluble, catalytically-promoting metal component with a finely divided, high area, refractory oxide which is sufficiently dry to absorb essentially all of said solution. The catalyticallypromoting metal component of the resulting composite is converted to water-insoluble form while the composite is essentially devoid of unabsorbed solution. The composite is comminuted in the presence of an aqueous medium which is preferably acidic. The resulting slurry is used to deposit the catalytically-promoting metal-containing solids on the macrosize carrier, and the resulting material is dried and may be calcined.
