Direct liquefaction of coal involves the conversion of a hydrogen-poor solid to a liquid richer in hydrogen by a complex set of bond ruptures and a hydrogen transfer reactions. This paper reports a portion of a continuing effort to understand the utilization of hydrogen in direct liquefaction by tracing the transfer of hydrogen from the gas phase to polynuclear aromatic hydrocarbon (PAH) solvent components, and from these donor components to coal. In this portion of the effort, experiments were performed to monitor the dehydrogenation of hydroaromatic components of a coal-derived solvent that results form donation of hydrogen to coal.
