摘要： A process for producing phenol and/or cyclohexanone by cleaving cyclohexylbenzene hydroperoxide in a loop cleavage reactor comprising multiple reaction zones connected in series. In desirable embodiments, fresh cyclohexylbenzene hydroperoxide feed(s) are supplied to reaction zones the final reaction zone, and fresh acid catalyst is supplied only to the final reaction zone. In desirable embodiments, a portion of the effluent exiting the final reaction zone is recycled to the first reaction zone. Each reaction zone is equipped with a heat exchanger downstream of the feed port to extract heat generated from the cleavage reaction.

摘要： Disclosed herein is a process for dehydrogenating a hydrocarbon with a dehydrogenation catalyst comprising a step of activating the catalyst precursor in a H2-containing atmosphere. A particularly advantageous activation process includes heating the catalyst precursor to a temperature in a range from 400° C. to 600° C. The process of the present disclosure is particularly advantageous for dehydrogenating cyclohexane to make benzene.

摘要： In a process for producing phenol, benzene is hydroalkylated with hydrogen in the presence of a catalyst under conditions effective to produce a hydroalkylation reaction product comprising cyclohexylbenzene and cyclohexane. At least a portion of the cyclohexane from said hydroalkylation reaction product is then dehydrogenated to produce a dehydrogenation effluent comprising benzene, toluene and hydrogen. At least a portion of the dehydrogenation effluent is washed with a benzene-containing stream to transfer at least a portion of the toluene from the dehydrogenation effluent to the benzene-containing stream.

摘要： 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.
