The purpose of this work was to determine the effects of surface area variations of iron sulphides on coal liquefaction. Several iron sulphides were synthesized including pyrites (Fe!&) with 46.6 wt% Fe, pyrrhotites (Fe,.,S) with -60 wt% Fe and irortsulphur compounds of unknown composition. Surface

## Surface properties of sub-bituminous Wyodak and bituminous Illinois coals were examined using sorption and immersion techniques, to elucidate the effects of aqueous NaOH treatment. Sorption of non-polar gases such as CO;! and N, decreased significantly after the alkali treatment for the Wyodak
To elucidate the effect of mineral matter in coal on coal liquefaction, the thermal decomposition of some model compounds of coal structure, aromatic ethers and carbonyl compounds, has been carried out in tetralin solvent and in the presence of coal ash obtained by low temperature combustion. The co
