ABSTRACT:
A process for producing a monoalkylation aromatic product, such as ethylbenzene and cumene, utilizing an alkylation reactor zone and a transalkylation zone in series or a combined alkylation and transalkylation reactor zone. This process requires significantly less total aromatics distillation and recycle as compared to the prior art.
