ABSTRACT:
Mononuclear aromatic hydrocarbons, e.g. benzene and analogs, are converted by hydroalkylation to the corresponding cycloalkyl 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.degree. to 600.degree. C. prior to the hydroalkylation reaction.
