This report summarizes the progress of the Exploratory Research on Solvent Refined Coal Liquefaction project by The Pittsburgh and Midway Coal Mining Company's Merriam Laboratory for the period April 1, 1979 through June 30, 1979. Experimental work included a number of short residence time runs, but discussion of that work has been delayed until a later report. Experimental work reported focuses on an investigation of the decline in solvent quality experienced by the Wilsonville Pilot Plant during runs in support of the SRC I Demonstration Plant. A four run series was initiated with Wilsonville solvent; both the coal used at Wilsonville (Kentucky 6/11 - Pyro Mine) and Kentucky 9/14 coal from the Colonial Mine were used. The effect of pyrite addition to the Pyro Mine coal was investigated. No solvent quality or coking problems were experienced in the Merriam runs. Significant changes in solvent composition were apparent and equilibrated solvent samples were returned to Wilsonville for solvent quality testing.
