An apparatus for regenerating an ionic liquid catalyst comprising a reactive extraction column, the reactive extraction column comprising: (a) an upper feed port, wherein a slurry of an ionic liquid catalyst and an aluminum metal enter the reactive extraction column; (b) a lower feed port, wherein a solvent and optionally a hydrogen gas enter the reactive extraction column; (c) a moveable bed comprised of the aluminum metal between the upper and lower feed ports, wherein the ionic liquid catalyst and the aluminum metal reacts to free conjunct polymers from the ionic liquid catalyst and some of the freed conjunct polymers are extracted from the ionic liquid catalyst by the solvent to provide regenerated ionic liquid catalyst; (d) a lower exit port, wherein the regenerated ionic liquid catalyst exits the reactive extraction column; and (e) an upper exit port, wherein the solvent and freed conjunct polymers exit the reactive extraction column.
