1. A process for the dehydrogenation of at least one dehydrogenatable compound selected from a ketone and a hydrocarbon consisting of hydrogen and carbon, the process comprising contacting a feed comprising the at least one dehydrogenatable compound with a catalyst comprising an inorganic oxide support, a first component comprising at least one metal component selected from Group 1 and Group 2 of the Periodic Table of Elements, and a second component comprising at least one metal component selected from Groups 6 to 10 of the Periodic Table of Elements under dehydrogenation conditions effective to convert at least part of the at least one dehydrogenatable compound in the feed, wherein the catalyst is produced by a method comprising: (a) treating the support with the first component;(b) calcining the treated support at a temperature of about 100° C. to about 700° C.;(c) impregnating the support with the second component; and(d) calcining the impregnated support at a temperature of about 100° C. to about 700° C., wherein the impregnating (c) is effected after or at the same time as the treating (a). 2. The process of claim 1, wherein the inorganic support is at least one material selected from silica, a silicate, and an aluminosilicate. 3. The process of claim 1, wherein the inorganic support comprises silica. 4. The process of claim 1, wherein the second component comprises at least one metal component selected from platinum and palladium. 5. The process of claim 1, wherein the first component comprises a metal component comprising potassium. 6. The process of claim 1, wherein the calcining (b) is conducted in an oxygen-containing atmosphere. 7. The process of claim 1, wherein the calcining (d) is conducted in an oxygen-containing atmosphere. 8. The process of claim 1, wherein the dehydrogenation conditions include a temperature of about 250° C. to about 500° C., a pressure of about 100 to about 3550 kPa, a weight hourly space velocity of about 0.2 to 50 hr−1, and a hydrogen to cyclohexanone-containing feed molar ratio of about 2 to about 20. 9. A process for producing phenol from benzene, the process comprising: (i) contacting benzene and hydrogen with a catalyst under hydroalkylation conditions to produce cyclohexylbenzene;(ii) oxidizing cyclohexylbenzene from the contacting (i) to produce cyclohexylbenzene hydroperoxide;(iii) converting cyclohexylbenzene hydroperoxide from the oxidizing (ii) to produce an effluent steam comprising phenol and cyclohexanone; and(iv) contacting at least a portion of the effluent stream with a catalyst comprising an inorganic oxide support, a first component comprising at least one metal component selected from Group 1 and Group 2 of the Periodic Table of Elements, and a second component comprising at least one metal component selected from Groups 6 to 10 of the Periodic Table of Elements under dehydrogenation conditions effective to convert at least part of the cyclohexanone in the feed into phenol and hydrogen, wherein the catalyst is produced by a method comprising:(a) treating the support with the first component;(b) calcining the treated support at a temperature of about 100° C. to about 700° C.;(c) impregnating the support with the second component; and(d) calcining the impregnated support at a temperature of about 100° C. to about 700° C., wherein the impregnating (c) is effected after or at the same time as the treating (a). 10. The process of claim 9, wherein the inorganic support is selected from at least one material selected from silica, a silicate, and an aluminosilicate. 11. The process of claim 9, wherein the inorganic support comprises silica. 12. The process of claim 9, wherein the second component comprises at least one metal component selected from platinum and palladium. 13. The process of claim 9, wherein the first component comprises a metal component comprising potassium. 14. The process of claim 9, wherein the calcining (b) is conducted in an oxygen-containing atmosphere. 15. The process of claim 9, wherein the calcining (d) is conducted in an oxygen-containing atmosphere. 16. The process of claim 9, wherein the dehydrogenation conditions include a temperature of about 250° C. to about 500° C., a pressure of about 100 to about 3550 kPa, a weight hourly space velocity of about 0.2 to about 50 hr−1, and a hydrogen to cyclohexanone-containing feed molar ratio of about 2 to about 20. 17. The process of claim 9, wherein the effluent portion also comprises at least one compound selected from cyclohexanol, cyclohexenol, cyclohexenone and phenol. 18. The process of claim 9, and further comprising: (v) recycling at least part of the hydrogen produced in the contacting (iv) to the contacting (i). 19. The process of claim 1, wherein the at least one dehydrogenatable compound is selected from: cyclopropane, cyclopentane, methyl cyclopentane, cyclobutane, cyclopentene, cyclodecane, cyclohexane, methylcyclohexane, cyclododecane, cyclohexane, and cyclohexanone.
