Abstract
A method of making dialkylaromatics as a primary product is described. The design involves a dual reaction zone system, both reaction zones containing alkylation catalysts. The olefin feed is split into two portions (or two feeds are used), the first portion being fed to a first alkylation reaction zone and reacted with a first olefin. The other portion of olefin is reacted in a second reaction zone with the linear alkylaromatics formed in the first reaction zone to form the dialkylaromatics.
