An asphaltene-containing SRC-II coal liquid derived from Powhatan No. 5 mine coal and produced in the Ft. Lewis demonstration plant has been selected for study of catalytic hydroprocessing reactions. Analytical separation by liquid chromatography is being carried out to produce nine distinct fractions from 1 kg of coal liquid. These fractions will be used as feeds to high-pressure catalytic flow microreactors. Hydroprocessing of polynuclear aromatic hydrocarbons under industrially relevant conditions has shown that these 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. Hydroprocessing of solutions containing the following combinations of compounds has also been studied: quinoline/indole, quinoline/indole/dibenzothiophene, and quinoline/indole/naphthalene. Four of the types of compounds, or potential lumps, in coal-derived liquids are basic nitrogen, nonbasic nitrogen, sulfur, and aromatic compounds. It is desired to determine how these compounds interact and compete with each other in hydroprocessing and how these interactions depend on hydrogen partial pressure. Four model compounds, quinoline, indole, dibenzothiophene, and naphthalene, have been selected to represent compounds in each group. These compounds, in different proportions with hydrogen, were allowed to react in a batch autoclave reactor.
