摘要：A process to reduce utility consumption in the catalytic alkylation of benzene with propylene to form cumene. Propylene and benzene are reacted in an alkylation reaction zone, the effluent of which is divided into two portions, the first being recirculated to the inlet of the reaction zone and the cond being pasd into a paration zone wherein cumene product, di- and triisopropylbenzene and excess benzene are parated. A portion of the excess benzene is recycled to the inlet of the alkylation reaction zone, and a cond portion is admixed with di- and triisopropylbenzene and pasd into a transalkylation zone, the effluent of which is introduced into the paration zone. Utility consumption is reduced compared to prior art process, as a result of a reduction of the portion of excess benzene parated and recycled to the alkylation reaction zone.
