    Abstract: The invention relates to a method for the continuous hydrogenation of unsaturated compounds, according to which particles of a first hydrogenating catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved. According to the invention, the liquid phase is guided through a packed bubble column, in the presence of a hydrogenous gas which is subjected to a first partial hydrogen pressure and is at a first temperature in the parallel flow in the opposite direction to the gravitational force, the substance discharged from the bubble column reactor is subjected to a gas-liquid separation, and the liquid phase is then subjected to a transversal filtration, whereby a retentate and a filtrate are obtained. The retentate is introduced back into the bubble reactor, and the filtrate is guided over a bed of a second hydrogenating catalyst in the presence of a hydrogenous gas subjected to a second hydrogen partial pressure and at a second temperature, the second hydrogen partial pressure being at least 10 bar higher than the first hydrogen partial pressure.
