Abstract
An improved catalyst comprising a Group VIII noble metal, such as palladium, and rhenium is supported on a high surface area graphitized carbon. In an embodiment the Group VIII metal, e.g., palladium, has an average crystallite size in the range from 30 to 150 Angstroms. A process for making a catalyst is provided in which a support is impregnated with a solution of a Group VIII metal compound, the solvent is removed and the Group VIII metal impregnated support is impregnated with a solution of a rhenium compound using a solvent in which the Group VIII metal compound is insoluble, and thereafter the solvent is removed.
