abstract |
The present invention relates to a process for the preparation of a porous alumina support by impregnating a porous transition alumina support with an aqueous solution of a copper ammine complex, draining excess impregnation solution, and then heating the impregnated support to a temperature above 80 & To a copper / alumina composition for use, for example, as a catalyst, prepared by depositing on a pore surface of a support. The composition of the present invention has a high surface area based on the unit weight of copper in the composition after reduction. |
