The thermal and catalytic chemistry of napthalene, indan, indene, benzothiophene, o-cresol, benzofuran and quinoline has been investigated to help elucidate the reactions occurring during the coprocessing of coal and petroleum. Hydrogenation reactions were conducted. Three sets of reactions were performed: thermal, thermal with sulfur and catalytic with Mo naphthenate as an oil-soluble catalyst precursor and added sulfur to generate the catalyst in situ. A reaction temperature of 380/sup 0/C and a hydrogen atmosphere of 1250 psig (cold) were used. Analysis of the solids generated from Mo naphthenate and sulfur amorphous and poorly crystalline molybdenum sulfide, most probably MoS/sub 2/; however, the exact stoichiometry is inknown. The thermal reaction was performed as a baseline and to evaluate the thermal interactions among the various hydrocarbon and heteroatomic species; the thermal reaction with sulfur was performed to ascertain the effect of excess sulfur on the system since the catalytic system required excess sulfur to form the in situ generated catalyst; and the catalytic reaction was performed to determine the interactive chemistry of the hydrocarbons and heteroatomic species under catalytic coprocessing conditions. 13 refs., 14 figs., 10 tabs.
