This report summarizes the progress of the Exploratory Research on Solvent Refined Coal Liquefaction project by The Pittsburg and Midway Coal Mining Co.'s Merriam Laboratory for the period January 1, 1980 through March 31, 1980. A series of experiments was conducted with three western coals to study the relationship between coal properties and liquefaction behavior. All three coals were low in iron (0.2 to 0.4%, dry coal basis) and processing in both the SRC I and SRC II modes does not appear to be feasible at normal conditions without added catalyst. Adding 1 to 2% pyrite to the feed slurry increased oil yields considerably while reducing SRC and IOM yields and improved operability. Product quality was also generally improved by the catalyst. Operability and oil yields were generally found to be better at 450/sup 0/C than at 465/sup 0/C.
