The hydrogenation of phenanthrene in the presence of 24 kPa of ammonia was studied during the hydrodenitrogenation (HDN) of quinoline on a sulfided NiMo/Al{sub 2}O{sub 3} catalyst at 360{degrees}C, 6.9 MPa total H{sub 2} pressure in a vapor phase tubular reactor. Ammonia, through competitive adsorption, reduced the formation of phenanthrene hydrogenated products and the hydrocracking of 9,10-dihydrophenanthrene to biphenyl. The effects occur largely when the HDN reactions are substantially completed. 6 refs., 8 figs., 1 tab.
