This report presents operating conditions and test results for the six-ton-per-day Solvent-Refined Coal (SRC) pilot plant at Wilsonville, Alabama, during the first quarter of 1977. Amax Belle Ayr subbituminous coal processing was completed. The effects of varying the dissolver volume and the partial pressure of hydrogen sulfide were determined for this coal. Processing of Emery coal, to produce 66 tons of ''reconstituted coal'' (equivalent to unfiltered SRC), was begun. Filter cakes generated by processing both of these coals have lower resistances to flow than those produced when processing eastern coals during 1976. Cake resistance appears to be a function of the fraction of unconverted coal in the solids. Results of testing alternate methods for mineral residue separation, as well as future plans for solids separation, are discussed.
