Coal cleaning effects during H-Coal catalytic liquefaction of a western Kentucky coal. [Effect of coal cleaning on oil yield]
Two H-Coal bench-scale liquefaction tests were performed to compare the hydroliquefaction behavior of two Kentucky No. 11 coals from the same mine: a run-of-mine coal with 17.49 W % ash and a deep-cleaned coal with 6.21 W % ash. The tests were conducted using a syncrude mode of operation. The deep-cleaned coal exhibited greater coal conversion and greater residual oil yield than the run-of-mine coal. On a dry coal basis, the deep-cleansed coal yielded approximately 19% more C/sub 4/ to 975/sup 0/F distillate than the run-of-mine coal. The process requirement of a pumpable vacuum still bottoms product would result in a 10% higher C/sub 4/ to 975/sup 0/F yield from the deep-cleaned coal than from the run-of-mine coal in a commercial H-Coal plant.
