Electrochemical removal of unsaturated beipolymeren ausionischen chloroaluminate fluid`s

A process for regenerating a spent ionic liquid catalyst comprising (a) applying a voltage to one or more pairs of electrodes which are immersed in a spent ionic liquid catalyst containing complexes of unsaturated Beipolymeren and metal halides, so as to obtain liberated unsaturated Beipolymere and a regenerated ionic liquid catalyst; and (b) separating the released unsaturated polymers of the regenerated ionic liquid catalyst. Furthermore, an alkylation process comprising the regeneration process.
