  • Dehydrogenation process
    Patent number: 9580368
    Abstract: 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.
    Type: Grant

  • Process for producing phenol
    Patent number: 8884075
    Abstract: 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.
