In order to evaluate the effect of intermolecular cohesion on the conversion of bituminous coal, the reactivity of oxygen-methylated and reductively methylated coals were tested by non-catalytic liquefaction reaction in tetralin solvent at 693K. The yield of oil fraction from oxygen-methylated and reductively methylated coals were increased by 12 and 22wt%, respectively, compared to the raw coal. The increment of oil fraction corresponds to the acceleration of the hydrogenolysis reaction form preasphalten to oil. The effect of hydrogen bonds in bituminous coal on its hydrogenolyisis reaction made about half contributions to oil yield compared with the others such as van der Waals and charge transfer interaction.
