Abstract: In a process for producing cyclohexylbenzene, hydrogen, and benzene are contacted in a first reaction zone under conditions effective to produce a product effluent containing residual benzene in the vapor phase and cyclohexylbenzene in the liquid phase. The product effluent is separated into a first stream that is rich in residual benzene in the vapor phase as compared to the product effluent and a second stream that is rich in cyclohexylbenzene in the liquid phase as compared to the product effluent. At least a portion of the first stream is cooled to condense at least a portion of the residual benzene in the vapor phase to the liquid phase and produce a condensate stream. At least a portion of the condensate stream is recycled to the first reaction zone.

Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.
