ABSTRACT OF THE DISCLOSURE The coal liquefaction process and apparatus therefor, of the type which includes a slurry mixing tank, a preheater, a hydrogenation reactor, and a gas-liquid-solid separator or separators. A gas-liquid separator and a solid-liquid separator or separators are interposed between the hydrogenation reactor and a dehydrogenation-cyclic-polymerization reactor which is positioned upstream of a final gas liquid-solid separator. In the hydrogenation reactor, a mixture of coal fines and a hydrocarbon solvent which are preheated to 300° to 500°C is subjected to a hydrogenation reaction under a pressure of 50 to 700 atms.in the presence of hydrogen. In this reactor, particular consideration is given to the equilibrium level of an interface between a solid rich layer and a solid lean layer which are separated therein so as to allow an efficient, con- tinuous liquefaction reaction. In the solid rich layer, a hydrogenation reaction is promoted, while a dehydrogenation- cyclic-polymerization reaction takes place in the solid lean layer. In the liquid-solid separator system, two separators are provided to be operated alternately for improving the opera- tional efficiency. In the dehydrogenation-cyclic-polymerization reactor, a liquid residum is subjected to the dehydrogenation- cyclic-polymerization reaction in the presence of hydrogen of a low partial pressure at a temperature of 400° to 500°C and a pressure of 50 to 700 atms.
