The progress of the Solvent Refined Coal (SRC) Project by The Pittsburg and Midway Coal Mining Co. for the Energy Research and Development Administration for the period January 1, 1977 to March 31, 1977 is summarized. Activities include the operation and modification of the Solvent Refined Coal Pilot Plant at Fort Lewis, Washington and process development work at the laboratory in Merriam, Kansas. The Fort Lewis SRC Pilot Plant was operated only 14 days during January prior to being shut down for SRC II modification. During the January operating period, the filtration test program begun in late 1976 was completed. Results of the program are presented. For the remainder of the quarter the pilot plant underwent extensive inspection, repairs, and modification in preparation for SRC II operation. In the SRC II process, formerly referred to as the slurry recycle mode of operation, a portion of unfiltered coal solution will be recycled to the slurry preparation area. The longer residence time of the slurry, the somewhat higher reaction pressure, and the recycle of unfiltered coal solution yield a liquid fuel as the principal product. Process development work at the Merriam Laboratory has defined the operating parameters for SRC II operation using Kentucky No. 9 coal. A brief series of trials using the Amax coal in an SRC I mode of operation was also begun. A summary of the Merriam SRC II work is presented. The plant operated for 14 days during January to generate filtration data using B filter and the Johnson Screen. Reactor area conditions were held at a constant 3500 lb/hr coal feed and a 1.6 solvent-to-coal ratio to provide a consistent filter feed. Ninety-four tons of specification SRC were produced during this period. Analytical data from the January operating period are presented in tables. Only waste treatment units were in operation the entire quarter.
