    Abstract: In a process for producing phenol and cyclohexanone, a cleavage feed containing greater than 40 wt % and no greater than 95 wt % cyclohexyl-1-phenyl-1-hydroperoxide, and at least 5 wt % and less than 60 wt % cyclohexylbenzene is mixed with at least phenol, cyclohexanone, water, and sulfuric acid to produce a cleavage reaction mixture containing from 15 wt % to 50 wt % phenol, from 15 wt % to 50 wt % cyclohexanone, from 1 wt % to 10 wt % cyclohexyl-1-phenyl-1-hydroperoxide, from 5 wt % to 60 wt % cyclohexylbenzene, from 0.1 wt % to 4 wt % water, and from 10 wppm to 1000 wppm sulfuric acid. The cleavage reaction mixture is then reacted at a temperature from 30° C. and to 70° C., and a pressure of at least 1 atmosphere for a time sufficient to convert at least 50% of said cyclohexyl-1-phenyl-1-hydroperoxide in said cleavage reaction mixture and produce a cleavage effluent containing phenol and cyclohexanone.

    Abstract: In a process for separating methylcyclopentanone from a mixture comprising methylcyclopentanone and cyclohexanone, a feedstock comprising cyclohexanone, methylcyclopentanone, water at a concentration of at least 0.10 wt %, and optionally phenol is fed into a fractionation distillation column, where a lower effluent rich in cyclohexanone and an upper effluent rich in methylcyclopentanone are produced. Due to the inclusion of water at a relatively high concentration in the feedstock, efficient separation of methylcyclopentanone is achieved. In certain particularly desirable embodiments, the lower effluent is substantially free of methylcyclopentanone. The thus produced cyclohexanone may be used to make, e.g., high-purity caprolactam, which, in turn, may be used for fabricating, e.g., high-performance nylon-6 material.

    Abstract: A hydrocarbon feed can be contacted with dehydrogenation catalyst particles to produce a conversion effluent that includes coked catalyst particles and dehydrogenated hydrocarbon(s). The coked catalyst particles can be contacted with an oxidant and a fuel to produce a combustion effluent that can include catalyst particles lean in coke and a combustion gas. The catalyst particles lean in coke can be contacted with an oxidative gas at an oxidizing temperature for a duration of at least 30 seconds to produce conditioned catalyst particles that can have an activity that can be less than the coked catalyst particles. The conditioned catalyst particles can be contacted with a reducing gas to produce regenerated catalyst particles that can have a dehydrogenation activity that can be greater than the coked catalyst particles. The dehydrogenated hydrocarbon(s) can be cooled, compressed, and a plurality of products can be separated from the compressed gaseous stream.
