Patent ID: 6919294

Claim:
A method for producing a hydrorefining catalyst containing an inorganic oxide carrier and a hydrogenation-active metal, the catalyst comprising pores having pore diameters of not more than 50 nm have a pore volume of not less than 0.4 cm 3 /g, pores having pore diameters of not less than 50 nm have a pore volume of not less than 0.2 cm 3 /g, and pores having pore diameters of not less than 1000 nm have a pore volume of not more than 0.1 cm 3 /g, the method comprising the steps of: mixing and forming a pseudo-boehmite powder having a dispersibility index of 0.13 to 0.28; and calcinating the formed pseudo-boehmite powder under a condition in which the pseudo-boehmite powder is converted into γ-alumina.
