Solvent Refined Coal (SRC) process. Research and development report No. 53, interim report No. 29, August-November, 1978. Volume VI. Process development unit studies. Part 1
This report presents the results of seven SRC-II runs on Process Development Unit P99 feeding Pittsburgh Seam coal. Four of these runs (Runs 41-44) were made feeding coal from the Robinson Run Mine and three (Runs 45-47) were made feeding a second shipment of coal from the Powhatan No. 5 Mine. This work showed that both these coals are satisfactory feedstocks for the SRC-II process. Increasing dissolver outlet hydrogen partial pressure from approximately 1300 to about 1400 psia did not have a significant effect on yields from Robinson Run coal, but simultaneously increasing coal concentration in the feed slurry from 25 to 30 wt% and decreasing the percent recycle solids from 21% to 17% lowered distillate yields. With the Powhatan coal, a modest increase in the boiling temperature (approximately 35/sup 0/F) at the 10% point) of the process solvent had essentially no effect on product yields, while lowering the average dissolver temperature from 851/sup 0/F to 842/sup 0/F reduced gas yield.
