Enhanced Coal Liquefaction by Pyrolysis in Supercritical Fluids. Quarterly Report, January-March 1986

摘要

This research program involves a fundamental investigation of a novel coal liquefaction process that combines pyrolysis and supercritical-fluid solvent extraction. The experimental work consists of determining: (1) coal pyrolysis reaction pathways, kinetics and mechanisms; (2) equilibrium solubilities of coal-related compounds (e.g., primary liquefaction products) in supercritical water and solvent mixtures containing selected primary liquefaction products with supercritical water. Experiments involving model coal compounds will be accomplished to determine the fundamental factors associated with the mild pyrolysis of coal in supercritical fluids with the aim of developing optimal conversion strategies for actual coals. 3 figs.
