ABSTRACT:
A process for enhancing the activity of a catalyst metal particulate for hydrogenation reactions comprising calcining the particulate in an oxidant-containing atmosphere to partially oxidize it thereby forming a porous layer of oxides thereon, treating with an solution capable of oxidizing the calcined metal particulate and comprising a compound of a hydrogenation catalyst metal to where said metal particulate has absorbed a volume of solution equal to at least about 10% of its calculated pore volume and activating it by treatment with a hydrogen-containing gas at elevated temperatures thereby forming a dispersed active metal catalyst. Preferably, the treated particulate is calcined a second time under the same conditions as the first before final activation with a hydrogen-containing gas. The metal particulate is preferably sized after each calcination and any agglomerates larger than 250 microns are comminuted to a desired size.
