The contribution of transferable hydrogen in coal-derived solvents to coal conversion was investigated in a two-step process. Initially, the amount of transferable hydrogen in the coal-derived solvents was analyzed by spectroscopic methods and by catalytic dehydrogenation. The spectroscopic methods included carbon magnetic resonance, proton magnetic resonance as well as a combination of these two methods. Three of the methods gave nearly equivalent quantities for the amount of transferable hydrogen present in the complex coal liquids. Coal conversion determined in each of the coal-derived solvents was correlated to the amount of transferable hydrogen present. The contribution of transferable hydrogen is a significant factor in coal dissolution and the presence of saturates and hexane insolubles compounds in these solvents may have a detrimental effect on coal dissolution. 20 references, 9 figures, 2 tables.
