The ultimate objective of this research is to uncover new catalytic processes for the liquefaction of coal and for upgrading coal-derived fuels by removing undesirable organosulfur, organonitrogen and organooxygen constituents. Accordingly, this study is exploring how crucial hydrogen-transfer processes might be catalyzed by soluble, low-valent transition metal complexes and/or Lewis acids under moderate conditions of temperature and pressure. By learning the mechanism whereby H{sub 2}, metal hydrides or partially hydrogenated aromatics do transfer hydrogen to model aromatic compounds, with the aid of homogeneous, bimetallic catalysts, we hope to identify new methods for producing superior fuels from coal. This quarter, an initial survey of the Lewis acid-catalyzed hydrogen transfer between aromatic and hydroaromatic hydrocarbons was completed. Ongoing work is attempting to anchor such aluminum Lewis acids to surfaces, so that hydrogen transfer of coal liquids might be achieved by percolation through a catalytic-bed reactor.
