HYDROALKYLATION OF BENZENE AND ANALOGS Mononuclear aromatic hydrocarbons, e.g. benzene and analogs, are converted by hydroalkylation to the corresponding cycloaklyl aromatics by contacting the mononuclear aromatic hydrocarbons in the presence of hydrogen with a catalyst comprising a rare earth-exchanged Y-type zeolite support carrying a promoter comprising at least one of ruthenium, iridium, rhodium and palladium, the catalyst being calcined in an oxygen-containing atmosphere at a temperature of 250 to 600.degree.C prior to the hydroalkylation reaction. |
