METHOD FOR PREPARING HYDROGENATION PURIFICATION CATALYST |
摘要 |
A method is used to produce a hydrorefining catalyst containing an inorganic oxide carrier and a hydrogenation-active metal in which pores having pore diameters of not more than 50 nm have a pore volume of not less than 0.4 cm3/g, pores having pore diameters of not less than 50 nm have a pore volume of not less than 0.2 cm3/g, and pores having pore diameters of not less than 1000 nm have a pore volume of not more than 0.1 cm3/g. The method comprises the steps of mixing and forming a pseudo-boehmite powder in which a crystallite diameter in a (020) direction is 2.0 to 3.0 nm, and a crystallite diameter in a (120) direction is 3.2 to 4.8 nm; and calcinating the formed pseudo-boehmite under a condition in which the pseudo-boehmite is converted into .gamma.-alumina.
