    Abstract: PROBLEM TO BE SOLVED: To provide a method for continuously hydrogenating an unsaturated compound with integrated advantages including a high space-time yield, a high conversion ratio with improved methodological versatility, and small investment cost.
    SOLUTION: The method for continuously hydrogenating unsaturated compounds involves: (a) particles of a first hydrogenation catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved, the liquid phase, in the presence of a hydrogenous gas at a first partial hydrogen pressure and at a first temperature, is conducted through a conductive pipe 4 to a packed bubble column reactor in cocurrent counter to the direction of gravity, (c) the effluent from the bubble column reactor is sent to a gas-liquid separation tank 8, (d) the liquid phase from step (c) is sent to a crossfiltration 12 to obtain a retentate 11 and a filtrate 13, (e) the retentate is recycled to step (b), and (f) the filtrate, in the presence of a hydrogenous gas at a second partial hydrogen pressure and at a second temperature, is passed over a bed 18 of a second hydrogenation catalyst.
