Abstract: A process for producing an alkylated aromatic compound comprises contacting an aromatic starting material and hydrogen with a plurality of catalyst particles under hydroalkylation conditions to produce an effluent comprising the alkylated aromatic compound, the catalyst comprising a composite of a solid acid, an inorganic oxide different from the solid acid and a hydrogenation metal, wherein the distribution of the hydrogenation metal in at least 60 wt % of the catalyst particles is such that the average concentration of the hydrogenation metal in the rim portion of a given catalyst particle is Crim, the average concentration of the hydrogenation metal in the outer portion of a given catalyst particle is Couter, the average concentration of the hydrogenation metal in the center portion of the given catalyst particle is Ccenter, where Crim/Ccenter≧2.0 and/or Couter/Ccenter2.0. Also disclosed are rimmed catalyst and process for making phenol and/or cyclohexanone using the catalyst.

Abstract: A process for activating a hydroalkylation catalyst in a first state comprising an acid component and a hydrogenating metal component, including: (i) treatment at a temperature of at least 120° C. in the presence of hydrogen for a first duration to produce a catalyst in a second state having a first hydroalkylation activity; (ii) contacting the catalyst in the second state with an aromatic compound and hydrogen under a hydroalkylation condition effective to convert at least part of the aromatic compound to a cycloalkylaromatic compound and produce a catalyst in a third state; and (iii) treating the catalyst in the third state at a temperature of at least 160° C. in the presence of hydrogen but advantageously in the substantial absence of the aromatic compound for a third duration to produce an activated catalyst in a fourth state having a third hydroalkylation activity greater than the first hydroalkylation activity.

Abstract: The present invention relates to hydrogenation processes including: contacting a first composition with hydrogen under hydrogenation conditions, in the presence of an eggshell hydrogenation catalyst, wherein the first composition has: (i) greater than about 50 wt % of cyclohexylbenzene, the wt % based upon the total weight of the first composition; and (ii) greater than about 0.3 wt % of cyclohexenylbenzene, the wt % based upon the total weight of the first composition; and thereby obtaining a second composition having less cyclohexenylbenzene than the first composition. Other hydrogenation processes are also described.
