Abstract

A system for making cyclohexylbenzene starting from benzene and hydrogen includes a first benzene preparation column, a hydroalkylation reactor, a dehydrogenation reactor, a second distillation column for cyclohexylbenzene separation, a third distillation column for cyclohexylbenzene purification, a transalkylation reactor, and a fourth distillation column for separating cyclohexylbenzene from transalkylation effluent. All components are integrated to achieve a high-purity cyclohexylbenzene product produced with a high yield and high overall energy efficiency.
