A method utilizing supercritical carbon dioxide for impregnating coal with catalytic amounts of molybdenum hexacarbonyl useful for promoting coal dissolution during direct liquefaction is described. Results are presented that describe the solubility and phase behavior of molybdenum hexacarbonyl in supercritical carbon dioxide at 40{degrees}, 50{degrees}, and 60{degrees}C. A model based upon the Peng-Robinson equation of state was used to both initially predict and subsequently model the observed solubility behavior. Preliminary liquefaction results of Illinois No. 6 coal impregnated with molybdenum carbonyl from supercritical carbon dioxide are also presented.
