Phosphorous-doped NiMo/γ-Al 2 O 3 catalyst prepared using ethylene glycol (EG) as additive was tested in the hydrotreating of straight-run gas oil. The organic agent was diluted in the impregnation solution obtained by the dissolving of MoO 3 and Ni(OH) 2 in water solution of H 3 PO 4 . The TEM data confirmed that the procedures used in catalyst preparation and sulfidation ensure the formation of highly dispersed NiMoS nanoparticles. As determined by X-ray photoelectron spectroscopy, the addition of EG leads to the formation of sulfide catalyst with a higher dispersion of Mo on the surface. Accordingly, the catalyst with EG is more active in hydrodesulfurization and hydrodenitrogenation of straight-run gas oil than the catalyst prepared without one.
