A process for the liquefaction of solid carbonaceous material, e.g., coal in the presence of hydrogen under pressure in the absence of heterogeneous hydrogenation catalyst using a hydrogen transfer solvent which is the fraction extracted from coal derived liquids by a process derived naphtha extractant containing less than 20 weight percent of aromatics. Coal derived liquids are extracted with naphtha and recycled as a slurry medium for the carbonaceous material. |
