Zusammenfassung:A zeolite-based ethylbenzene process which is suitable for retrofiaing aluminum chloride-based ethylbenzene plants. The process involves alkylating benzene with ethylene in an alkylation zone in the presence of zeolite beta or Y or an MCM zeolite so as to produce an alkylation product mixture containing benzene, ethylbenzcne, and polyethylbenzenes which can be separated in the aromatics recovery (distillation) stage of an aluminum chloride-based plant. The polyethylbenzenes are subsequently contacted with benzene in a transalkylati on zone using zeolite beta or mordenite or Y so as to produce a transalkylation product mixture which is also separable in the aromatics recovery stage of an aluminum chloride-based plant.
