This report summarizes the progress of the Solvent Refined Coal (SRC) project by The Pittsburg and Midway Coal Mining Co. under contract with the Department of Energy. The Fort Lewis Pilot Plant continued to operate in the SRC-II mode processing Powhatan No. 6 Mine coal until April 27. In the SRC-II Preheater B test program, two baseline runs and five slurry runs were completed as a part of the high heat flux run series. After a scheduled three week shutdown, the plant resumed operation May 24 in the SRC-I mode. The SRC-I Preheater B test program began June 1 and fourteen baseline runs and eight slurry runs were completed. This test program was temporarily suspended June 26 because of coil skin thermocouple problems. Work achieved on Process Development Unit P-99 this period included completion of a study to determine the effect of L/D ratio on yields. In addition, three runs (P99-67, -68, -69) were made feeding Powhatan No. 6 Mine coal, and two runs (P99-70 and -71) were made feeding Ireland Mine coal. Research and development technical support services accomplished are as follows. Modeling and simulation studies have addressed the areas of temperature gain in a SRC-II reactor, the recycle system, application of the steady state CSTR thermal response model, and development of a comprehensive model for coal liquefaction in SRC-II mode. Work was initiated on a process cost model of a commercial SRC-II plant which will be used for optimization studies and for guiding R and D projects. Several process parameters have been investigated using pressure differential scanning calorimetric/thermogravimetric techniques to study coking tendencies of SRC-II streams.
