Coal or a similar solid carbonaceous feed material is converted into lower molecular weight liquid hydrocarbons by contacting the feed material with a hydrogen-donor solvent containing above about 0.6 weight percent donatable hydrogen and molecular hydrogen in a liquefaction zone or a series of two or more liquefaction zones under liquefaction conditions in the presence of an added carbon-alkali metal catalyst comprising a carbonalkali metal reaction product prepared by heating an intimate mixture of carbonaceous solids and an alkali metal constituent to a temperature above about 800/sup 0/F in a reaction zone external to the liquefaction zone.
