A process for carrying out catalytic hydrogenation reactions involving as three phases a suspended catalyst, the hydrogen-carrying gas and the substance to be hydrogenated travelling in concurrent relationship is characterized in that the heterogeneous mixture is forced through a reaction zone at a flow rate of at least 0.5 metre/sec. The process is described with reference to the hydrogenation of cyclohexene to cyclohexane in the presence of Raney Ni.ALSO:A process for carrying out catalytic hydrogenation reactions involving as three phases a suspended catalyst, the hydrogen-carrying gas and the substance to be hydrogenated travelling in concurrent relationship is characterized in that the heterogeneous mixture is forced through a reaction zone at a flow rate of at least 0.5 metre/second. The process is described with reference to H2O2 from redox of alkyl anthraquinones in the presence of Pd black.ALSO:A process for carrying out catalytic hydrogenation reactions involving as three phases a suspended catalyst, the hydrogen-carrying gas and the substance to be hydrogenated travelling in concurrent relationship is characterized in that the heterogeneous mixture is forced through a reaction zone at a flow rate of at least 0.5 metre/sec.
