AN ALKYLATING PROCESS FOR ALKYL BENZENES

摘要

Provided is an alkylbenzene alkylation method, comprising the steps of: a) enabling alkylbenzene and a first portion of alkylation agent to enter a first reaction area and contact a catalyst A to produce a material stream I; b) enabling the material stream I and a second portion of alkylation agent to enter a second reaction area and contact a catalyst B to produce a material stream II; and c) enabling the material stream II to enter at least a third reaction area and contact a catalyst C to produce a material stream III containing the alkylated product. The above alkylation method has a high alkylation agent utilization rate.
