FIELD: petrochemical processes.
SUBSTANCE: alkylation and transalkylation reactions are carried out in one step by charging mixture of two different catalysts into one reactor: first alkylation catalyst EBEMAX-1 and then transalkylation catalyst EBEMAX-2 at their weight ratio (5-1):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.
