Title: Method of treating intermetallic alloy hydrogenation/oxidation catalysts for improved impurity poisoning resistance, regeneration and increased activity

Abstract

The present invention is directed to a method of treating intermetallic alloy hydrogenation/oxidation catalysts with successive oxidation catalysts with successive oxidation and hydrogenation steps at increased temperature to make the intermetallic alloy hydrogenation or oxidation catalysts less susceptible to deactivation by gas impurities, such as hydrogen sulfide; to increase the ability of the hydrogenation and oxidation catalysts to regenerate after sulfur poisoning; and to increase the activity of the hydrogenation and oxidation catalysts to a point close to their original activities after gas impurity poisoning and regeneration. The treatment processes of the present invention are particularly useful for nickel-containing intermetallic alloy hydrogenation catalysts and platinum-containing intermetallic alloy hydrogenation catalysts and best results are obtained for the zirconium/nickel intermetallic alloy hydrogenation catalysts. 23 figs.
