Supercritical fluids for reaction and extraction of coal and heavy oils. First annual report, September 1, 1981-September 1, 1982
A program for the study of supercritical extraction is being carried out. Emphasis is placed on developing a fundamental understanding of supercritical extraction for coal conversion and for coal liquid deashing. Basic thermodynamic models of supercritical solutions have been extended to mixtures, and experimental study of model systems is underway; for example, supercritical extraction of naphthalene, phenol mixtures using ethylene and other solvents will be conducted. Based upon these studies various models used for describing the supercritical extraction of more complex mixtures such as coal fractions, heavy oils and shale oils will be evaluated. Initial experiments have used supercritical water to convert coal and glucose to liquids (THF solubles) and gases at temperatures near 374/sup 0/C. Models will be developed based upon the experimental studies of these systems.
