摘要： Disclosed herein is a process for dehydrogenating a saturated cyclic hydrocarbon and/or 5-membered ring compound with a dehydrogenation catalyst. The dehydrogenation catalyst comprises: (i) 0.05 wt % to 5 wt % of a metal selected from Group 14 of the Periodic Table of Elements; and (ii) 0.1 wt % to 10 wt % of a metal selected from Groups 6 to 10 of the Periodic Table of Elements. The process is conducted under dehydrogenation conditions effective to dehydrogenate at least a portion saturated cyclic hydrocarbon and/or 5-membered ring compound.

摘要： In a process for the dehydrogenation of cyclohexanone to produce phenol, cyclohexanone is contacted in a reaction zone under dehydrogenation conditions with a dehydrogenation catalyst comprising (i) a support comprising silica; and (ii) a dehydrogenation component comprising at least one metal selected from Group 10 of Periodic Table of Elements. Contact of the dehydrogenation catalyst with the cyclohexanone is then terminated and the dehydrogenation catalyst is contacted with an inert gas and/or hydrogen at a temperature of at least 300° C. Contact of the dehydrogenation catalyst with additional cyclohexanone is subsequently reestablished.

摘要： Provided is a process for making cyclohexylbenzene. The process includes the following steps: (a) contacting benzene and hydrogen in the presence of a first catalyst under hydroalkylation conditions sufficient to form a first effluent stream having cyclohexylbenzene, cyclohexane, methyl cyclopentane, and unreacted benzene; (b) supplying at least part of said first effluent stream to a first separation system to divide said first effluent stream part into a cyclohexane/methylcyclopentane-rich stream, a cyclohexane-rich stream, a benzene-rich stream, and a dicyclohexyl benzene-rich stream; (c) recycling at least part of the benzene-rich stream to the contacting step (a); (d) contacting the cyclohexane/methylcyclopentane-rich stream with a second catalyst that catalyzes dehydrogenation and exhibits low acidity under conditions sufficient to convert at least a portion of the cyclohexane to benzene and at least a portion of the methylcyclopentane to linear and/or branched paraffins to form a second effluent stream; and (e) recycling at least part of the second effluent stream to the contacting step (a).
