The role of tin catalysts has been studied for the hydroliquefaction of a West Virginia coal in batch autoclave experiments with tetralin and tin catalysts. Two competing reactions are found to play important roles in the autoclave system. These are (1) hydrogen transfer from tetralin to coal, and (2) dehydrogenation/hydrogenation in the reaction Tetralin=Naphthalene + 2H/sub 2/. In the absence of initial molecular H/sub 2/ but in the presence of SnCl/sub 2/, dehydrogenation of tetralin is catalyzed by an interaction of SnCl/sub 2/ and coal. This dehydrogenation is favored, and the coal conversion (to toluene-solubles plus gases) and hydrogen transfer (to coal) are lower than in the non-catalytic control run. When both SnCl/sub 2/ and high pressure of H/sub 2/ are present, hydrogen transfer from tetralin to coal becomes a favorable reaction, and the spent solvent is rehydrogenated by the molecular H/sub 2/.
