ABSTRACT OF THE DISCLOSURE Process for producing fluid fuel from coal. Moisture- free coal in particulate form is slurried with a hydrogen-donor solvent and the heated slurry is charged into a drum wherein the pressure is so regulated as to maintain a portion of the solvent in liquid form. During extraction of the hydrocarbons from the coal, additional solvent is added to agitate the drum mass and keep it up to temperature. Subsequently, the pres- sure is released to vaporize the solvent and at least a por- tion of the hydrocarbons extracted. The temperature of the mass in the drum is then raised under conditions required to crack the hydrocarbons in the drum and to produce, after sub- sequent stripping, a solid coke residue. The hydrocarbon pro- ducts are removed and fractionated into several cuts, one of which is hydrotreated to form the required hydrogen-donor sol- vent while other fractions can be hydrotreated or hydrocracked to produce a synthetic crude product. The heaviest fraction can be used to produce ash-free coke especially adapted for hydrogen manufacture. The process can be made self-sufficient in hydrogen and furnishes as a by-product a solid carbonaceous material with a useful heating value. -2-
