Abstract: Disclosed are processes for making cyclohexanone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, 3-cylclohexenone and optionally 2-cyclohexenone, comprising feeding the feed mixture to a first distillation column and hydrogenating a fraction from the first distillation column in a hydrogenation reactor separate from the first distillation in the presence of a hydrogenation catalyst under hydrogenation conditions. A cyclohexanone-rich upper effluent comprising 3-cyclohexenone and 2-cyclohexenone at low concentrations can be obtained from the first distillation column.

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.

Abstract: This invention relates to processes and systems for converting acyclic hydrocarbons to alkenes, cyclic hydrocarbons and/or aromatics, for example converting acyclic C5 hydrocarbons to cyclopentadiene in a reactor system. The process includes contacting a feedstock comprising acyclic hydrocarbons with a catalyst material and an inert material to convert at least a portion of the acyclic hydrocarbons to a first effluent comprising alkenes, cyclic hydrocarbons and/or aromatics. In particular, the catalyst material and the inert material have a different average diameter and/or density providing varying fluidization behavior in the reactor.

Abstract: Method for concentrating an organic hydroperoxide mixture comprising a hydrocarbon and a hydroperoxide corresponding thereto comprises evaporating a first liquid mixture in a thin-film evaporation device followed by separation in a separation zone. Both the evaporation device and the separation zone operate at a low absolute pressure at a temperature lower than the thermal degradation temperature of the hydroperoxide to prevent thermal decomposition thereof. The process is particularly useful for concentrating an oxidation product made from the oxidation of cyclohexylbenzene.

Abstract: A cyclohexane dehydrogenation process comprising a step of providing, as a benzene-containing stream, a vapor phase in equilibrium with a liquid phase at a condensation separation system; supplying benzene, hydrogen, and cyclohexane into a dehydrogenation reactor where at least part of the benzene supplied is from the benzene-containing stream. The use of a condensation separation system enables the control of the partial pressure of benzene in the material fed into the dehydrogenation reactor by controlling the temperature of the vapor phase, and hence the control of hydrogen to benzene molar ratio in the dehydrogenation reactor. The process results in a long life of the dehydrogenation catalyst due to reduced coking.

Abstract: In a process for producing phenol, a cleavage feed comprising cyclohexylbenzene hydroperoxide is supplied to a cleavage reaction zone and a cleavage reaction mixture comprising the cleavage feed is contacted in the cleavage reaction zone with a solid acid catalyst under conditions effective to produce a cleavage effluent comprising phenol and cyclohexanone. The cleavage effluent is then divided into at least a cleavage product and a cleavage recycle and the cleavage recycle and a polar solvent is supplied to the cleavage reaction zone to produce the cleavage reaction mixture with the cleavage feed. Preferably, the polar solvent is combined with the cleavage recycle before being charged into the cleavage reaction zone.
