Abstract

Alkylation of an aromatic is provided in a reactor having a central alkylation zone, and a surrounding transalkylation zone. The reaction mixture flows cocurrently through the alkylation zone and then into the surrounding transalkylation zone, with the mixture flowing in approximate plug flow through the transalkylation zone to the outlet thereof. Polyalkyl aromatics recovered from the effluent are recycled to the inlet end of the transalkylation zone.
