20110021841 | Process for Producing Cyclohexylbenzene - In a process for producing cyclohexylbenzene, benzene and hydrogen are contacted with a catalyst under hydroalkylation conditions to produce an effluent containing cyclohexylbenzene. The catalyst comprises a composite of a molecular sieve, an inorganic oxide different from said molecular sieve and at least one hydrogenation metal, wherein at least 50 wt % of said hydrogenation metal is supported on the inorganic oxide and the inorganic oxide has an average particle size less than 40 μm (microns). | 01-27-2011 |
20110037022 | Process for Producing Phenol and/or Cyclohexanone - In a process for producing phenol and/or cyclohexanone, benzene and hydrogen are contacted with a first catalyst in a hydroalkylation step to produce a first effluent stream comprising cyclohexylbenzene, cyclohexane, and unreacted benzene. At least part of the first effluent stream is supplied to a first separation system to divide the first effluent stream part into a cyclohexylbenzene-rich stream and a C6 product stream comprising unreacted benzene and cyclohexane. | 02-17-2011 |
20110105805 | Process for Producing Phenol - In a process for producing phenol, cyclohexylbenzene is oxidized to produce cyclohexylbenzene hydroperoxide and then the resultant cyclohexylbenzene hydroperoxide is cleaved to produce an effluent stream comprising phenol and cyclohexanone. At least a portion of the effluent stream is then fed to at least one dehydrogenation reaction zone, where the effluent stream portion is contacted with a dehydrogenation catalyst under conditions effective to convert at least part of the cyclohexanone in the effluent portion into phenol and hydrogen. | 05-05-2011 |
20110288341 | Process For Producing Cyclohexylbenzene - 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. | 11-24-2011 |
