Abstract: We provide a process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers in a reactor, by removing at least 57 wt % of the conjunct polymers originally present in the used acidic ionic liquid catalyst in a separate regeneration reactor, so as to increase the activity of the catalyst. We also provide a regenerated used acidic ionic liquid catalyst having increased activity.
