Some conversion and hydrogenation reactivity of benzofuran was observed in the thermal reaction with sulfur. However, catalytic reaction with Mo naphthenate was required for substantial, nearly 50%, hydrogenation, complete hydrogenolysis and high levels, approx.80%, deoxygenation. The introduction of benzothiophene and o-cresol lowered both hydrogenation and deoxygenation while the addition of quinoline markedly reduced hydrogenation, virtually eliminated deoxygenation and slightly reduced hydrogenolysis. Quinoline, by contrast to all of the other compounds studied, produced substantial thermal hydrogenation to THQ; however, the introduction of both hydrocarbons and heteroatomics reduced the conversion of quinoline to THQ. The presence of the oxygen containing compounds nearly eliminated the conversion of quinoline to THQ. Similar results were observed in the thermal reactions with sulfur. Catalytically, quinoline was readily hydrogenated and denitrogenated. The addition of both hydrocarbons and heteroatomics had little influence on the quinoline reaction except for the introduction of benzothiophene at higher reactant levels. When added to a catalytic reaction of naphthalene and quinoline, the addition of benzothiophene reduced the catalyst poisoning effects of quinoline. The hydrogenation of naphthalene double while the hydrogenation, hydrogenolysis and denitrogenation of quinoline were all improved. 15 refs.
