In a kind of method producing phenol, in the presence of hydroalkylation catalyst, under conditions of effectively producing the hydroalkylation effluent comprising cyclohexyl benzene, benzene, hydrogen and methane, benzene is reacted with hydrogeneous methane source.From this hydroalkylation effluent, remove the first stream comprising hydrogen, methane and benzene, and this first stream is cleaned the hydrogen stream of the lean benzene that generation contains hydrogen and methane and containing cyclohexyl benzene and the purge stream of benzene by the second stream containing cyclohexyl benzene. |
