Abstract
The present invention is related to a process of fuel oil hydrodesulfurization and hydrodenitrogenation, wherein a cobalt-Molybdenum catalyst is prepared on a carrier of titanium-zirconium-vanadium mixed oxides, and the reaction is carried out in a fixed-bed reactor under reaction conditions. The present invention discloses the operating conditions of desulfurization and denitrogenation reactions, and the optimal compositions of said catalysts as well as its preparation method.
