摘要：
Experimental studies on the coprocessing of a subbituminous coal with liquid fractions derived from Athabasca bitumen are described. The reactions were carried out in a batch autoclave under hydrogen pressure at reaction temperatures varying from 400 to 440 degrees C. Net coal conversion was higher and coke formation was lower when the coal was processed with the Pentane soluble maltene fractions compared to that obtained with the virgin bitumen. Among the maltene fractions, the polyaromatics provided the highest liquid yield, followed by the mono/di aromatics. The polyaromatics also provided the highest coke yields. The saturates provided the highest gas yields and the lowest liquid yields. H/C ratio of various products were the highest when the polyaromatic fractions were used as the solvent.
