ABSTRACT:
A process for regenerating a used acidic ionic liquid catalyst comprising contacting the used ionic liquid catalyst with at least one ‘regeneration’ metal in a regeneration zone in the presence of added hydrogen under regeneration conditions for a time sufficient to increase the activity of the ionic liquid catalyst is described. In one embodiment, regeneration is conducted in the presence of a hydrocarbon solvent.
