Title:
PROCESS FOR MAKING ALKYLATED AROMATIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2014/158985
Kind Code:
A8
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 center portion of the given catalyst particle is Ccenter, where 0.2 < Crim/Ccenter < 2.0. Also disclosed are hydroalkylation catalyst and process for making phenol and/or cyclohexanone using the catalyst.
