Beschreibung
Zusammenfassung:	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.10 cl, 3 ex, 3 dwg Изобретение относится к способу алкилирования бензола этиленом. Способ включает: обеспечение разбавленного потока этилена, содержащего между 5 и 50 масс.% этилена; обеспечение потока бензола, содержащего по крайней мере 3 масс.% толуола и по крайней мере 20 масс.% парафинов; взаимодействие потока разбавленного этилена и потока бензола с катализатором алкилирования, содержащим UZM-8; и превращение по крайней мере 20% бензола в сырьевом потоке в алкилбензол. Также изобретение относится к устройству для алкилирования бензола этиленом. Использование настоящего изобретения позволяет устранить использование отгонной колонны реформата, что приводит к существенным эксплуатационным и капитальным сбережениям. 2 н. и 8 з.п. ф-лы, 3 пр., 3 ил.
