Copper/alumina compositions for uses as e.g. catalysts are made by impregnating a porous transition alumina support with an aqueous solution of a copper ammine carbonate complex, draining off any excess of the impregnating solution, and then heating the impregnated support to a temperature above 80° C to decompose the complex thereby depositing a basic copper carbonate compound on the surfaces of the pores of the transition alumina support. After reduction, the composition have a high copper surface area, expressed per unit weight of copper in the composition. |
