The present invention is directed to catalysts for hydrodesulfurization and hydrodenitrogenation of hydrocarbon oils with high catalytic activity, excellent productivity and low pollution. The invention also provides a method of preparing said catalysts. The catalysts according to the present invention comprise an alumina carrier substance, at least one active metal element selected from the Group VI metals in the Periodic Table, at least one active metal element chosen from the Group VIII metals in the Periodic Table, phosphoric acid, and an additive agent. Said additive agent is at least one substance selected from a group consisting of dihydric or trihydric alcohols having 2 ~ 10 carbon atoms per molecule, ethers of the alcohols, monosaccharides, disaccharides, and polysaccharides. The present invention also provides a method for preparing said catalysts by impregnating said alumina carrier substance with a solution mixed with a certain amount of the active metal elements, phosphoric acid and the additive agent and drying the impregnated carrier substances at a temperature of less than 200°C.
