Patent
·
OSTI ID:5912803
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. The partially liquefied solid carbonaceous material may be taken from the bottoms fraction of the effluent from any of the liquefaction stages.
