Abstract
The effect of the introduction of V2O5 in the Ni-Мo/Al2O3 catalysts on their activity in hydrofining reactions of petroleum raw materials was studied. The activity in hydrodesulphurization and hydrogenation of polycyclic aromatic hydrocarbons (PAHs) of straight-run diesel fraction and light coker gas oil was determined. A high degree of hydrodesulphurisation and high degree of hydrogenation of PAHs in the presence of the Ni-MoV/ɣ-Al2O3 catalysts were detected. It was determined that when using various molybdenum compounds the catalyst synthesized using H3[VMo12O40] . H2O possessed the highest activity in hydrodesulphurisation and hydrogenation of PAHs.
