A process is described for the hydrodenitrogenation of a hydrocarbon stream containing a substantial amount of nitrogen compounds. The process comprises contacting the stream in a reaction zone in the presence of hydrogen and under hydrodenitrogenation conditions with a catalyst comprising a hydrogenation component comprising chromium, molybdenum, and at least one metal from Group VIII of the Periodic Table of Elements deposited upon a porous alumina-silica support. The silica of the support is present in an amount within the range of about 10 wt% to about 50 wt%, based upon the weight of the support, the chromium molybdenum, and metal from Group VIII being present in the elemental form, as oxides, as sulfides, or mixtures thereof. The catalyst has a surface area within the range of about 150 m/sup 2//gm to about 350 m/sup 2//gm, a pore volume within the range of about 0.4 cc/gm to about 1.0 cc/gm, an average pore diameter within the range of about 60 A (6 nm) to about 150 A (15 nm). The volume of pores having a diameter of 60 A (6 nm) to 150 A (15 nm) is less than 80% of the volume of pores having a diameter of 0 A () nm) to 150 A (15 nm), the volume of pores having a diameter of 150 A (15 nm) to 1,200 A (120 nm) is greater than 0.01 cc/gm.
