Abstract

A process for regenerating a palladium catalyst from a catalytic reaction where the catalyst is contaminated with at least carbon. The regenerating is conducted prior to any heating step under oxidizing conditions in the regenerating section. The regenerating involves at least one heating step under a hydrogen-containing reducing atmosphere and under conditions sufficient to lower the content of carbon in the palladium catalyst.
