    摘要： The invention relates to a method for hydrogenating an aromatic compound. The invention in particular relates to a method for preparing cyclohexanone, cyclohexanol or a mixture thereof in a continuous way by catalytically hydrogenating phenol fed into a reactor comprising a supported hydrogenation catalyst, comprising a dopant selected from the group of alkali metal hydroxides, alkaline earth metal hydroxides, alkaline earth metal oxides, carbonates of alkali metals and carbonates of alkaline earth metals, and in which process during the hydrogenation of phenol continuously or intermittently water is fed into the reactor, the weight to weight ratio of water fed into the reactor to phenol fed into the reactor on average being 0.1 or less.

    摘要： The present invention provides a novel method of hydrogenating a phenol for hydrogenating a phenol industrially advantageously. The present invention relates, in the case of phenol hydrogenation in which carbon dioxide is made to participate in the reaction, to a method of hydrogenating a phenol characterized by using a supported rhodium and/or ruthenium catalyst, whereby the phenol is hydrogenated efficiently at a lower reaction temperature than with prior art; such a method characterized in that carbon dioxide having a temperature of 20 to 250° C. and a pressure of 0.1 to 50 MPa is used as the carbon dioxide; and such a method characterized in that hydrogen under conditions of a temperature of 20 to 250° C. and a pressure of 0.1 to 50 MPa is used.An environmentally friendly phenol hydrogenation process that uses no harmful organic solvents can be realized.
