A bituminous and a sub-bituminous coal were liquefied in the presence of hydrogen donor solvents. Statistical analyses of the data showed that for contact times up to 10 min, the coal conversion, measured in terms of tetrahydrofuran solubles, was not significantly different for the two coals. The hydrogen-donating capacity of the solvent was varied by the addition of hydrogenated phenanthrene to SRC-II recycle solvent. The results indicated that there are two routes for the formation of oils from coal: the preferred route depends on the hydrogen-donating capacity of the solvent. The kinetic model proposed in Part I is extended to account for the change in the donor capacity of the solvent.
