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 1):
A process for making cyclohexanone, the process comprising the following steps:\n (I) feeding a first mixture comprising cyclohexanone, phenol, and cyclohexylbenzene into a first distillation column; (II) obtaining from the first distillation column: a first upper effluent comprising cyclohexanone at a concentration higher than the first mixture; a first middle effluent comprising cyclohexanone, phenol at a concentration higher than the first mixture, cyclohexylbenzene, and bicyclohexane; and a first lower effluent comprising cyclohexylbenzene at a concentration higher than the first mixture; (III) obtaining a hydrogenation feed from at least a portion of the first middle effluent; (IV) subjecting the hydrogenation feed to one or more pre-hydrogenation treatments; (V) feeding at least a portion of the treated hydrogenation feed and hydrogen into a hydrogenation reaction zone where the portion of the treated hydrogenation feed contacts a hydrogenation catalyst under hydrogenation reaction conditions such that phenol reacts with the hydrogen in the presence of the catalyst so as to obtain a hydrogenation reaction product comprising cyclohexanone at a concentration higher than the concentration of cyclohexanone in the treated hydrogenation feed, phenol at a concentration lower than the concentration of phenol in the treated hydrogenation feed, cyclohexylbenzene, and bicyclohexane; and (VI) feeding at least a portion of the hydrogenation reaction product into the first distillation column,\n wherein each of the one or more pre-hydrogenation treatments is selected from the following: (i) contacting the hydrogenation feed with one or more posterior sorbents; (ii) contacting the hydrogenation feed with one or more posterior distillation columns; (iii) adding to the hydrogenation feed a basic chemical agent selected from the group consisting of amines, inorganic bases, and mixtures thereof; and (iv) adding water to the hydrogenation feed such that water is present in the treated hydrogenation feed in an amount ranging from 0.1 wt % to 20 wt %, based on the weight of the hydrogenation feed.
