Data from an experimental study of coal-derived residuum reactivity are reported. Thermal conversion experiments were completed at short contact time reaction conditions using eight residuum samples derived from Kentucky 9/14 and Illinois 6 bituminous coals. Results indicated that residuum reactivity toward distillate production decreased with increase severity of catalytic prehydrotreatment. Asphaltene disproportionation and retrogressive reactions to form insoluble organic matter were suppressed when the feed residuum was hydrotreated prior to thermal conversion. Results from elemental analysis and Fourier Transform Infrared spectroscopic measurements on selected asphaltene samples suggested that disproportionation occurred via a mechanism of phenolic condensation.
