In a process for the dehydrogenation of dehydrogenatable hydrocarbons, a feed comprising dehydrogenatable hydrocarbons is contacted with a catalyst comprising a support and a dehydrogenation component under dehydrogenation conditions effective to convert at least a portion of the dehydrogenatable hydrocarbons in the feed. The catalyst is produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid.

Dehydrogenation process

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&#xb0; C. Contact of the dehydrogenation catalyst with additional cyclohexanone is subsequently reestablished.
