REACTIVATION OF NOBLE METAL-CONTAINING CATALYST MATERIALS ABSTRACT OF THE DISCLOSURE A coke-deactivated noble metal-containing catalyst is sulfided with a sulfiding agent, e.g., H2S in H2, then coke is burned from the sulfided catalyst by contacting the catalyst with oxygen and then the catalyst is reduced with a reducing agent, e.g., H2. The process permits burning off coke while avoiding excessive agglomeration of the noble metals on the catalyst.
