A series of [gamma]-Al[sub 2]O[sub 3]-supported molybdenum and nickel sulfide catalysts was prepared in order to investigate the role of the nickel promoter and the effect of the sulfur feed compounds on the hydro-denitrogenation (HDN) performance of Ni-Mo/[gamma]-Al[sub 2]O[sub 3] catalysts. The reactions performed were pyridine HDN, thiophene HDS, HDN in the presence of thiophene, and HDN in the presence of H[sub 2]S. The catalysts were characterized using laser Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, BET surface area measurement, and temperature-programmed desorption of H[sub s]S thiophene, and pyridine. The results of the reaction studies and characterization experiments are combined with earlier reports in the literature to propose an explanation of the role of nickel and gas phase sulfur compounds in pyridine HDN network. 47 refs., 16 figs., 1 tab.
