BENZENE-VIA-ETHYLENE ALKYLATION PROCESS Russian patent published in 2005 - IPC

Abstract RU 2261853 C1

FIELD: petrochemical processes.

SUBSTANCE: alkylation and transalkylation reactions are carried out in one step by charging mixture of two different catalysts into one reactor: alkylation catalyst EBEMAX-1 and transalkylation catalyst EBEMAX-2 at their weight ratio (20-1):1. Process is carried out at 380-450°C.

EFFECT: increased yield of ethylbenzene and alkylation selectivity while simultaneously reduced power consumption and process expenses.
