ABSTRACT:
Catalysts for hydrodesulfurization and hydrodenitrogenation of hydrocarbon oils are provided which have high catalytic activity, excellent productivity and low pollution. The catalysts are made from 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. The additive agent is at least one substance selected from dihydric or trihydric alcohols having 2-10 carbon atoms per one molecule, ethers of the alcohols, monosaccharides, disaccharides, and polysaccharides. A method for preparing the catalysts is also provided and includes impregnating the 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 substance at a temperature of less than 200.degree. C.
