The effect of phosphorus on Mo₂C supported on {gamma}-Al₂O₃ and activated carbon was studied. The catalysts were characterized by CO chemisorption, BET surface area measurements, x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), and tested for their reactivity for hydroprocessing reactions, particularly hydrogenation (HYD), hydrodesulfurization (HDS) and hydrodenitrogenation (HDN), using model liquid compounds. The P-containing catalysts had higher reactivity for HDN than those without P. HDS was higher when the Mo₂ C was synthesized on {gamma}-Al₂ O₃ previously treated with P than when the Mo component and P were added together on {gamma}-Al₂O₃. Post reaction characterization indicates that the catalysts were tolerant of sulfur.
