N2 - Liquefaction of a semifusinite-rich lithotype of the Peach Orchard coal from Magoffin County, Kentucky, indicated conversions at high temperatures and long residence times was a consequence of vitrinite, liptinite, and semifusinite reactivity. The percentage of oils and gases were similar to that produced at lower severity from a Springfield (Western Kentucky No. 9) coal. Semifusinite is converted to vitroplast and anisotropic semicoke in the liquefaction of an DGC inertinite concentrate and to anisotropic semicoke in the liquefaction of the parent coal. Granular residue increases in concentration in the higher severity residues.
