Dehydrogenation process
First Claim
1. A process for the dehydrogenation of at least one dehydrogenatable hydrocarbon, the process comprising contacting a feed comprising the at least one dehydrogenatable hydrocarbon under dehydrogenation conditions with a catalyst composition free of germanium comprising a support and a dehydrogenation component comprising at least one metal component selected from platinum and palladium, wherein said conditions include a temperature of from 400°
- C. to 750°
C. and a pressure of at least 50 psig, the catalyst composition has an oxygen chemisorption of greater than 50%.

21. A process for producing phenol, the process comprising:
-
(a) oxidizing cyclohexylbenzene to produce cyclohexylbenzene hydroperoxide; (b) converting at least a portion of cyclohexylbenzene hydroperoxide from (a) to produce an effluent stream comprising phenol and cyclohexanone; and (c) contacting at least a portion of said effluent stream with a catalyst composition free of germanium comprising a support, a dehydrogenation component comprising at least one metal component comprising at least one metal component selected from platinum and palladium and an inorganic base component comprising at least one metal component selected from Group 1 and Group 2 of the Periodic Table of Elements under dehydrogenation conditions effective to convert at least at least a portion of the cyclohexanone in said feed into phenol and hydrogen; wherein said dehydrogenation conditions include a temperature of at least 450°
C. and a pressure of at least 90 psig, the catalyst composition has an oxygen chemisorption of greater than 50%. - View Dependent Claims (22)
