FIELD: chemistry.
SUBSTANCE: method includes supplying diluted flow of ethylene, which contains between 5 and 50 wt % of ethylene; supplying benzol flow, containing,at least 3 wt % of toluol and, at least, 20 wt % of paraffins; interaction of diluted ethylene flow and benzol flow with catalyst of alkylation, which contains UZM-8; and conversion of, at least, 20% of benzol in raw material flow into alkylbenzol. Invention also relates to device for alkylation of benzol with ethylene.
EFFECT: application of claimed invention makes it possible to eliminate application of reformate by fractionation column, which leads to essential exploitation and financial savings.
