;
The method of presulfiding of a commercial nickel molybdenum/alumina (NiMo/Al/sub 2/O/sub 3/) catalyst has a significant effect on its inherent activity for the hydrodenitrogenation (HDN) or quinoline. In addition, during reaction the addition of nitrogen sulfide increases on the kinetics of a variety of hydrodenitrogenation, hydrodesulfurization, and hydrogenation reactions on molybdenum catalysts can be rationalized in terms of its effect on two kinds of sites, sulfur anion vacancies and Broensted acids. 7 figures, 1 table.
