Supercritical fluid thermodynamics for coal processing. Quarterly progress report, July 1, 1990--September 30, 1990

Because of their unusual solvating and mass transfer properties, supercritical fluids show potential for a variety of coal processing applications. We have established a database of coal model compound equilibria; to add to this database, we have developed and are testing techniques of measuring entrainer effects on solubility rapidly. In addition, we have used fluorescence spectroscopy to study the nature of entrainer effects on a molecular level. The solubility and spectroscopic measurements are being used in the development of an equation of state that includes both physical and chemical interactions; we are currently testing the equation. The equation of state will be used to predict solubility behavior so systems can be designed for the processing of coal with supercritical fluids. 3 figs.
