In a process for directly liquefying coal, a paste consisting of finely divided coal, catalyst and heavy oil can be treated for thermal cracking and hydrocracking with a high liquid/space ratio and short residence time in a preheating section and a reaction section. An apparatus threfor comprises a plural number of pipe units having apertures for hydrogen injection and apertures for the paste of a low concentration or heavy oil injection and a gas-liquid separator for removing H.sub.2 O, methane, etc., the pipe units being formed in such a manner that a Reynolds number of 3.times.10.sup.3 or greater and an axial dispersion coefficient of 0.05 or smaller are achieved for the fluid flow therein.
