Work continued on the study of disposable catalysts and the effect of specific additives in both the SRC I and SRC II processing modes. At 450/sup 0/C, 2250 psig and 1.0 hour residence time with Loveridge coal in the SRC II mode, yields and hydrogen consumptions were essentially the same for runs with 5 wt % added pyrite or 3.3 wt % added ferric oxide. When Loveridge coal was impregnated with 0.7 wt % molybdenum, slightly higher oil yields and slightly lower hydrocarbon gas, SRC and IOM yields were obtained than with the iron compounds above. When Loveridge coal was processed in the SRC I mode at 450/sup 0/C, 1900 psig and 26 minutes residence time, there was a 3.7% increase in total oil yield with a corresponding decrease in SRC yield when pyrite was added to the feed slurry. There was a smaller effect with a FeS/sub 2//Fe/sub 2/O/sub 3/ combination and little or no effect when ferric oxide alone was added.
