Paulaitis, M E; Klein, M T; Sandler, S I

A fundamental investigation of a novel coal liquefaction process was undertaken which combines pyrolysis and supercritical-fluid solvent extraction. The experimental work consisted of determining: (1) coal pyrolysis reaction pathways, kinetics and mechanisms; (2) equilibrium solubilities of coal-related compounds in supercritical water. Experiments involving model coal compounds (tetralin and 1-methylnaphthalene, phenethyl phenyl ether, 1,3-diphenylpropane, benzyl phenyl ether, benzylamine). 8 refs., 6 figs., 9 tabs.
