An asphaltene-containing SRC II coal liquid from the Ft. Lewis demonstration plant has been selected for study of catalytic hydroprocessing reactions. Analytical separation of the liquid by liquid chromatography will be used to produce nine distinct fractions. These will be prepared from 1 kg of coal liquid and used individually as feeds to high-pressure flow microreactors. Hydroprocessing of polynuclear aromatic hydrocarbons under industrially relevant conditions has shown that they are much more reactive than benzene. The reaction networks involve reversible hydrogenation and isomerization, and significant concentrations of hydroaromatic (hydrogen-donor) species are attainable under practical conditions. Scanning electron microscopy combined with catalytic activity measurements (in hydroprocessing of dibenzothiophene and of quinoline) were used to characterize deactivated and regenerated Ni-Mo/Al/sub 2/O/sub 3/ catalysts (aged in the hydroprocessing of coal-derived liquids). EDAX results determined chemical composition of the catalyst and the deposited mineral crust. The hydroprocessing results indicate that regeneration of the catalysts can recover much of the activity lost as a result of coke formation.
