Reduced iron added at 14.3% by wt to a 1:2 coal/solvent (light recycle oil) slurry in coal liquefaction experiments with Kentucky bituminous coal carried out in a stirred (1000 rpm) autoclave at 410/sup 0/C and 2000 psig hydrogen was about as efficient a desulfurization agent as commercial Co-Mo-Al catalyst (Comox 451), by reacting directly with hydrogen sulfide. It increased the yields of the oil fraction and pyridine soluble products, because of the catalytic activity of the formed iron sulfides and in contrast to the more hydrogenation-selective Co-Mo-al, did not increase hydrogen consumption. SRC mineral residue from the filter cake of the Wilsonville SRC pilot plant was ineffective in hydrodesulfurization and increased hydrogen consumption. Adequate liquefaction yields (90 to 91%) and superior desulfurization rates were achieved at 380/sup 0/C and 1000 psi hydrogen. Iron is thus the prime candidate as the additive for the SRC I process, to produce a solid, low-sulfur boiler fuel with minimum hydrogen consumption. In the SRC II process, where a more hydrogenated liquid product is desired, the recycle of SRC residue would be preferred.
