An improved liquefaction process for solid carbonaceous materials wherein at least a portion of the liquefaction is accomplished in the presence of an added hydrogenation catalyst and a solvent containing at least 1.25 wt % donatable hydrogen and in the presence of partially liquefied, solid carbonaceous material at liquefaction conditions. In a preferred embodiment, the liquefaction is accomplished in a plurality of stages and a solvent containing at least 1.25 wt % donatable hydrogen is used in at least one stage, most preferably in the second stage.
