## Samples of Belle Ayr (WY) subbituminous and Powhatan No. 5 mine (Pittsburgh Seam) bituminous coals were dried with gases including nitrogen, air and nitrogen/air mixture at temperatures essentially from ambient to 200ยฐC as part of a study to measure liquefaction behaviour. While the oxygen upta

Low-temperature air autoxidation of SRC in quinoline followed by anaerobic thermolysis yields as much as 30% of low-molecular-might (<210) compounds. Preliminary autoxidation of the quinolinesoluble portion of a bituminous coal gave a significant yield of similar low-molecular-weight compounds. Thes
## Samples of partially dried and oxidized Belle Ayr subbituminous coal were liquefied in a recycle donor solvent (SK-II heavy distillate) to observe the effect of coal pretreatment on conversion. Because subbituminous coals have moisture contents typically > 25%, it would appear useful to dry the
