ABSTRACT OF THE DISCLOSURE In the liquefaction of a sub-bituminous and/or lignitic coal, prior to the liquefaction, the coal is soaked at a temperature of from 550° to 750° and a pressure of from 30 to 300 psig for a time sufficient to remove at least 10% of the organic oxygen present in the coal to thereby reduce the hydrogen requirements of the lique- faction. The liquefaction is effected with a pasting solvent derived from the sub-bituminous and/or lignitic coal having a 5 volume percent distillation temperature of at least 550°F and containing at least 25 weight percent of material boiling above 800°F. The use of such a pasting solvent provides for improved dispersion of the coal particles during the liquefaction. -i-
