ABSTRACT:
An ionic liquid catalyst, which has been regenerated by contacting a 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. Also, an ionic liquid catalyst which has been regenerated by contacting a used ionic liquid catalyst with at least one regeneration metal in a regeneration zone in the presence of added hydrogen under regeneration conditions in the presence of an inert hydrocarbon in which conjunct polymers are soluble for a time sufficient to increase the activity of the ionic liquid catalyst.
