The selectivity of a Mo/Al/sub 2/O/sub 3/ catalyst in denitrogenation, desulfurization, and deoxygenation based on the retarding effect of sulfur and oxygen compounds on acridine hydrodenitrogenation has been studied. The experiments were done in a continuous flow microreactor at 280-380/sup 0/C and 10.1 MPa total pressure. Sulfidation of the reduced catalyst hindered the denitrogenation of perhydroacridine to dicyclohexylmethane. The sulfur and oxygen compounds, except for a small amount of CS/sub 2/, depressed the denitrogenation at higher temperatures where the intermediate hydrogenations of acridine to perhydroacridine attained equilibria. At lower temperatures, all the additives affected the hydrogenation of octahydroacridine to perhydroacridine which was not at equilibrium and resulted in a decrease of denitrogenation. The kinetics and reaction mechanism of the retarding effects are also discussed.
