The liquefaction and hydrodesulphurization of a high sulphur Kentucky coal has been studied in batch autoclave experiments, with tetralin or methylnaphthalene as solvents, and several Co-Mo-Al/sub 2/O/sub 3/ catalysts. In tetralin, an excellent hydrogen-donor solvent, gas phase hydrogen and catalyst are still important in determining both the conversion of asphaltene to oil and the extent of desulphurization. Superimposed on other effects, the disproportionation of tetralin to naphthalene and decalin has been discovered to occur to approximately equilibrium at 455/sup 0/C, even in nitrogen and with no catalyst. Two commercial catalysts and two catalysts made from controlled pore size aluminas have been studied in coal hydrodesulphurization with methylnaphthalene as solvent, at a 1 percent catalyst level. Appreciable differences were observed in product distribution. The most favorable results were obtained with large pore diameter (200 A) catalyst, even though this had the lowest total surface area.
