Abstract:
Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.

Claim (Index 15):
The process of  claim 14 , wherein, when the treated hydrogenation feed is in mixed liquid and vapor phase while it contacts the hydrogenation catalyst, one or both of the following conditions is fulfilled: (1) the liquid mass flux through the hydrogenation catalyst is at least 2 kg/m 2 s; and (2) the liquid holdup in the hydrogenation reaction zone is maintained at greater than or equal to 1 vol %, the vol % based upon the available void volume in the hydrogenation catalyst within the hydrogenation reaction zone.
