ABSTRACT:
An improved method for regenerating acetylene hydrogenation catalysts which does not require an oxygenation step is provided. The method may be used to regenerate any acetylene hydrogenation catalyst; however, the method is particularly advantageous when used with a palladium based catalyst which has been used to remove acetylenic contaminants from ethylene.
