ABSTRACT An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process selected feed coal is pul-verized and slurried with a process derived solvent passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures following which solids including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75% by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.
