Computer simulation was applied for modeling of coal three- dimensional structure. The calculation of minimum energy conformation for coal soluble constituents showed that aggregates among coal molecules by association through van der Waals, hydrogen bonding and electrostatic interactions, were more stable structures than free molecules. Some organic compounds may attack the non-covalent bonds, and weaken or break them during solvent extraction or swelling, resulting in increases in extraction yields and swelling ratios of the coals. Coal molecule-organic compound interactions were evaluated by computer simulation.

We report here observation of morphological changes of coal surface during the solvents swelling by using AFM. We prepaed two different thin section coal samples, one is parallel and another is perpendicular to coal bed plane. We observed solvent swelling of these thin section coal sample. The swelling occurred perpendicular to bedding plane.

Miike and Taiheiyo coal was oxidized by oxygen or air at low temperature. Oxidized Taiheiyo coal was treated with methanol. Ion radiated Taiheiyo coal was also prepared. Depth profiling anlyses of the treated coals were carried out by using step scan FT-IR spectrometer equipped with a photoacoustic detector with a phase modulation technique. Variation of phase modulation frequency and phase angle gave considerably different spectra reflecting a depth profile of coal particle. It was indicated that oxidation reaction proceeds on the coal surface and a specific layer in which methanol adsorption and decarbonyl reaction tends to occur exists near surface.

Tow coal model compounds (dibenzylehter and benzylphenlehter) are pyrolyzed in the presence of three solvents (tetralin, heavy anthracene oil and hydrogenated heavy anthracene oil) at 300℃. The rates of pyrolysis was measured by gc analysis. The rate increase with heavy solvents reported previously was different with model compounds.

Dibenzothiophene was hydrodesulfurized using syngas and steam in the presence of decalin solvent and catalyst. With experiments in H_2-CO-D_2O system,it was found that the desulfurized products, biphenyl and cyclohexylbenzene, contained substantial amounts of deuterated compounds. These results indicate that active hydrogen producted via water-gas shift reaction as well as H_2 in gas phase could contribute to the hydrodesulfurization reaction.
