Effects of reaction time, temperature and pressure on the liquefaction reaction of Victorian brown coal in the presence of iron/sulfur catalyst were discussed from the viewpoint of the hydrogen transfer. The amount of transferred hydrogen from both solvent and H_2 to total products (H(t)) represented the progress of the liquefaction reaction. The transferred hydrogen from the solvent played important role under the conditions of lower H_2 pressure and shorter time. The optimum condition was found for the efficiency of hydrogen consumption by means of distillate yield/H(t) ratio because C_1-C_4 gas markedly increased at higher temperature. This condition depended on the hydrogen donor ability of the solvent.
