摘要

The main objectives of this research were to make Illinois No. 6 coal liquid or soluble with inexpensive reagents (e.g., solvolysis with methanol and acids), without high pressure equipment, and to see if our soluble products would be more reactive than whole coal in liquefaction processes. These efforts are unpromising. However, efforts to make coal soluble by oxidation with nitric acid gave encouraging results. When Illinois No. 6 and Wyodak coals were allowed to stand in sunlight for 282 days, 27% of the original weight and 32% of the original carbon were lost. Concurrent experiments in the dark at 24 exp 0 C indicate that these coals are fairly stable in air in the dark; light causes most of the oxidation. The solubility properties of these aged coals will not be available before the end of this grant period. Several other minor lines of work, some very interesting, are summarized in order of decreasing significance. 1 figure, 6 tables. (ERA citation 09:047319)
