    摘要： In a process for producing cyclohexylbenzene, hydrogen and a liquid feed comprising benzene are introduced into a reaction zone and are contacted in the reaction zone under hydroalkylation conditions to produce cyclohexylbenzene. An effluent stream comprising cyclohexylbenzene and unreacted benzene is removed from the reaction zone and is divided into at least first and second portions, wherein the mass ratio of the effluent stream first portion to the effluent stream second portion is at least 2:1. The effluent stream first portion is then cooled and the cooled effluent stream first portion is recycled to the reaction zone.

    摘要： In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone comprising a catalyst system which comprises a molecular sieve and at least one hydrogenation metal. The MCM-22 family molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom, and the hydrogenation metal is selected from the group consisting of palladium, ruthenium, nickel, zinc, tin, cobalt, and combinations of any two or more thereof. Hydroalkylation conditions of temperature and pressure are selected to produce a hydroalkylation conversion in a range of from about 15% to about 75% The benzene and hydrogen are then contacted in the at least one reaction zone under said selected hydroalkylation condition to produce an effluent containing cyclohexylbenzene.
