Abstract: Non-normal, branched paraffins (isoparaffins) are separated from hydrocarbon feeds comprising mixtures of isoparaffins and normal paraffins by the procedure involving the steps of contacting the hydrocarbon feed with one face of a non-selective, microporous partition barrier membrane while simultaneously contacting the opposite face of said membrane, preferably in countercurrent flow, with a polar solvent. The isoparaffins in the feed selectively permeate across the porous partition barrier membrane in response to the polar solvent to the solvent side of the membrane whereby a permeate enriched in isoparaffins and a retentate of decreased isoparaffin content as compared to the feed are obtained.

Abstract: Naphthenic hydrocarbons are separated from aliphatic rich hydrocarbon feeds comprising mixtures of naphthenes with paraffinic hydrocarbons by a membrane extraction process whereby the hydrocarbon feed is contacted with one face of a porous, non-selective partition barrier membrane while simultaneously contacting the other side of said membrane with a polar solvent such as ethylenediamine. The naphthenic hydrocarbon preferentially migrates through the porous membrane partition barrier in response to the polar solvent present on the permeate side of the barrier.

Abstract: The invention relates to hydroalkylation processes. In the processes, a hydrogen stream comprising hydrogen and an impurity is treated to reduce the amount of the impurity in the hydrogen stream. The hydrogen is then hydroalkylated with benzene to form at least some cyclohexylbenzene. The processes also relate to treating a benzene stream comprising benzene and an impurity with an adsorbent to reduce the amount of the impurity in the benzene stream. The hydroalkylation processes described herein may be used as part of a process to make phenol.

Abstract: A promoter can have utility in selective heterogeneous oxidation of arylalkyl hydrocarbons such as, for example, cyclohexyl benzene and/or sec-butyl benzene to form hydroperoxides. The promoter can include the product of contacting a solid support comprising a metal oxide surface and an iron compound. The solid support can include, for example, titanium dioxide and/or an iron oxide such as magnetite and can have magnetic susceptibility. A method for the oxidation of arylalkyl hydrocarbons to form hydroperoxides can include contacting 16 an arylalkyl hydrocarbon with oxygen in the presence of the promoter under catalytic oxidation conditions to form arylalkyl hydroperoxide, which can then be converted to phenol via cleavage 26. The method can include recovery 22 of the promoter from the arylalkyl hydroperoxide and can further include recycling the recovered promoter to the contacting 16. Where the solid support has magnetic susceptibility, the recovery 22 can include magnetic separation of the promoter.
