For this study, the interactive thermal and catalytic chemistry involved in coprocessing of coal and petroleum has been investigated using model systems representative of those present in coal and residuum in order to gain insight into the chemistry involved in thermal and catalytic coprocessing. The hydrogenation catalyst precursor chosen for this study was molybdenum naphthenate. The active catalytic species were generated in situ in the presence of excess elemental sulfur. The present report gives the results of the reactions of the model compounds of dibenzofuran, dibenzothiophene, fluorene, and carbazole under thermal catalytic reaction conditions by using molybdenum naphthenate in the presence of excess sulfur as the hydrogenation catalyst. The reaction pathways for the hydrogenation and heteroatom removal of the selected model compounds have been investigated. On the basis of experimental results, possible hydrogenation reaction pathways for the different model systems are proposed in this quarterly report. 14 refs., 4 figs., 24 tabs.
