Coal liquefaction experiments have been carried out in a stirred autoclave under nitrogen. Tetralin was employed as solvent, and the catalyst, when used, was ammonium paramolybdate (impregnated) or stannous chloride (powdered). Production of pentane-soluble oil was higher in the runs with catalysts, but the net hydrogen transfer from tetralin to coal was less when catalyst was used. Coal and powdered stannous chloride exhibited a marked synergistic effect on the dehydrogenation of tetralin. A free radical mechanism was suggested to explain this effect, and model experiments with bibenzyl (but no coal) gave results that were consistent with this mechanism. An apparent synergistic effect of coal and impregnated ammonium paramolybdate was shown to be attributable simply to improved distribution (higher surface area) of the impregnated catalyst.
