Spent aluminum chloride Friedel-Crafts catalyst is regenerated in an aromatic hydrocarbon medium by supplying of powdered metallic aluminum and hydrogen chloride, the product of regeneration being passed to a separation zone in which a catalytic complex of the hydrocarbon and aluminum chloride is taken from between an upper layer constituted by the hydrocarbon and a lower layer (which is recycled) constituted by a suspension of unreacted aluminum in such a complex. |
