• In order to study the effect of solvent on the liquefaction of coal as a function of coal rank, the liquefaction of five kinds of coals from carbon content of 66% to 83% were carried out in the presence of various aromatic solvents. It was found that three ring aromatic hydrocarbons were more powerful solvent for the liquefaction. Hydrogen donor solvents such as tetralin and hydrophenanthrenes were most effective of all solvents tested independent of coal rank. A mixture of hydrogen donor and polar compounds such as phenol and quinoline was confirmed to be effective to bituminous coal but not so effective to brown coal. It should be stressed that hydrogen donating property of solvent is most important for low rank coals. The chemical analyses of products have shown that the properties of solvent refined coal are a little affected by the quality of solvent.
