Abstract
A process for the regeneration of a catalyst containing a metal of the group consisting of rhodium and ruthenium employed in the hydrogenation of an organic compound possessing at least one carbon-to-carbon bond unsaturation in the presence of a methylene dichloride solvent is taught whereby the catalyst is regenerated after deactivation by contacting the deactivated catalyst first with a hydrogen-containing gas then with an oxygen-containing gas and finally with a hydrogen-containing gas.
