The key findings are summarized. In the experiments with added elemental sulfur or sulfur containing organic compounds, the reactor walls appeared to be sulfided. The sulfided walls showed catalytic activity for promoting hydrogenation reactions of the model systems. Additional sulfur added to the model systems had different effects depending upon the reaction occurring. Hydrogenation of naphthalene and quinoline were enhanced; deoxygenation of o-cresol was inhibited; and hydrogenation of benzothiophene was not affected. However, the product which required further hydrogenation was ethylbenzene whose hydrogenation was not readily promoted by molybdenum sulfide. Adding excess amounts of sulfur to model systems containing nitrogen bases which poison the MoS/sub 2/ catalyst may alleviate the effect of the poison to some extent. Two strong nitrogen bases, quinoline and pyridine severely poisoned the catalytic hydrogenation activity and the denitrogenation selectivity of the in situ generated MoS/sub 2/. 22 refs., 2 figs., 28 tabs.
