Coal liquefaction and hydrogenolysis of solvent were conducted by a batch and a benchscale continuous reactor. These experiments were curried out using decrystallized anthracene oil as a solvent and red-mud/sulfur as a catalyst under three kinds of initial pressure. Structural parameters for products were calculated by Brown-Ladner method. The hydrogenolysis of the solvent were accelerated using the continuous reactor under the same conditions. For coal liquefaction, high molecular weight materials were concentrated in oil fraction at 10MPa of initial pressure. However, increasing initial pressure from 10MPa to 20MPa was possible to prevent these materials from concentrating in oil fraction. In addition, hydrogenolysis of oil fraction was remarkably proceeded at 30MPa.
