This final report covers the results of research performed after October 1977 and deals specifically with the study of hydrogen transfer in coal conversion to liquids. In particular we investigated the two possible modes of hydrogen addition in coal liquefaction: ionic and nonionic H-transfer. Accordingly, we discuss coal conversion related to catalysis of the transfer by soluble transition metal salts in Task 1: Ionic Routes of Coal Conversion in CO/H/sub 2/O Systems and discuss H-transfer in tetralin-containing systems in Task 2: Hydrogen Transfer Intermediates in Coal Liquefaction. We suggest that the view of hydrogen transfer as taking place over a range of reaction routes including both ionic and nonionic paths is important in achieving the goals of moderation of conditions and general improvement of coal conversion technology. The observation of ionic hydrogen transfer in conversion systems is particularly important since such systems can use water in the conversion rather than a conventional organic H-donor. Three appendices are titled Possible Hydride Transfer in Coal Conversion Processes, Liquefaction of Bituminous Coal in Aqueous Systems, and Coal Solubilization at Short Reaction Times.
