The introduction of quinoline to the naphthalene/DMC system had a dramatic effect on the products produced during catalytic reactions. The amount of naphthalene hydrogenated to both tetralin and decalin was substantially reduced. Of the three heteroatomic species introduced the catalytic naphthalene/DMC system, quinoline had the greatest inhibiting effect on naphthalene hydrogenation. Benzothiophene had a greater effect than phenol which had the least. The presence of naphthalene and DMC appeared to enhance the amount of hydrodenitrogenation and hydrogenolysis occurring in the catalytic hydrogenation of quinoline. Binary systems of naphthalene/quinoline, tetralin/quinoline and DMC/quinoline did not show any such enhancement. In fact, the presence of DMC inhibited the denitrogenation and hydrogenolysis of quinoline. The presence of tetralin either introduced directly or produced from the hydrogenation of naphthalene in the system did not appear to affect the quinoline reaction pathway. Therefore, the promoting effect obtained by the combination of naphthalene/DMC and quinoline is not easily explained by hydrogen donor chemistry but involves complex interactions among the chemical components and the catalyst. Under themal conditions at 350/sup 0/C, quinoline underwent hydrogenation unlike the other species used in this study. Even though a large excess of hydrogen was present, the introduction of naphthalene and DMC reduced by half the amount of quinoline hydrogenation occurring thermally. 10 refs., 1 fig., 19 tabs.
