摘要： In a process for producing cyclohexylbenzene, benzene is contacted with hydrogen under hydroalkylation conditions effective to form a first effluent stream comprising cyclohexylbenzene, cyclohexane, methylcyclopentane, and unreacted benzene. At least a portion of the first effluent stream is contacted with a dehydrogenation catalyst under dehydrogenation conditions to convert at least a portion of the cyclohexane to benzene thereby forming a second effluent stream. The amount of methylcyclopentane in the second effluent stream is different by no more than 65% of the total amount of the portion of the first effluent stream, said amounts being on a weight basis. A methylcyclopentane-containing stream is removed from either the first or the second effluent stream and at least a portion of the second effluent stream containing benzene is recycled to the hydroalkylation step.

摘要： In a process for producing phenol, cyclohexylbenzene hydroperoxide is cleaved to produce a cleavage effluent stream comprising phenol and cyclohexanone and at least a portion of the cleavage effluent stream is fractionated to produce a first fraction richer in cyclohexanone than the cleavage effluent stream portion and a second fraction richer in phenol and depleted in cyclohexanone as compared with said cleavage effluent stream portion. At least a portion of the second fraction is then contacted with a dehydrogenation catalyst in a dehydrogenation reaction zone under dehydrogenation conditions effective to convert at least a portion of the cyclohexanone in said second fraction portion into phenol and cyclohexanol.

摘要： In a process for purifying a hydrogen stream, the stream is contacted with a first washing fluid in a first purification zone under conditions effective to transfer at least some water from the hydrogen stream to the first washing fluid, thereby transforming the hydrogen stream into a water-depleted hydrogen stream. At least a portion of the water-depleted hydrogen stream may then be transferred from the first purification zone to a second purification zone, where it is contacted with a second washing fluid under conditions effective to transfer at least some oxygenates from the water-depleted hydrogen stream to the second washing fluid.

摘要： Disclosed is a method for making olefin product from an oxygenate-containing feedstock. In the method, a silicoaluminophosphate molecular sieve catalyst is contacted with the oxygenate-containing feedstock in a reactor at an average catalyst feedstock exposure index of at least 1.0. The method produces lower coke yield and provides an olefin product which is low in C1-C4 paraffin content. The invention is particularly effective in producing an olefin product having a very low propane content.
