Abstract:
     The present invention relates to a recovery activating method of arene alkylate aluminium trichloride complex catalyst. It is characterized by that after the aluminium trichloride complex catalyst is wash-recovered by use of paraffin hydrocarbon, the fresh aluminium trichloride and alkyl benzenes are added partially so as to keep the catalyst activity. The alkylation reactive inversion ratio of the catalyst obtained from the recovery by use of said invention is high, and the dosage of aluminium trichloride is economic and its alkyl benzenes product quality is good.
