PURPOSE: To improve desulfurization activity by preparing a catalyst wherein at least one hydrogenation active metal component is carried on a silica-alumina carrier in such a way that the vol. of pores with diameters in a specified range measured by means of a mercury pressing method is made to be a specified ratio. CONSTITUTION: In a catalyst for processing of hydrogenation wherein at least one hydrogenation active metal component is carried on a carrier consisting of silica-alumina contg. 2-40wt.% silica, the specific surface area is 200-400<2> m/g, the total pore vol. is 0.40-0.55ml/g and the vol. of pores with a diameter of 0-300 angstrom (hereinbelow abbreviated as Å) is at least 75% of the vol. of pores with a diameter of 40Å or larger. In addition, the mean pore diameter of the pores with a diameter of 0-300Å is 40-90Å and the vol. of pores with a diameter of 300-150,000Å is 0.01-0.25ml/g. In addition, the vol. of pores with a diameter of 300-600Å is at least 40% of the vol. of pores with a diameter of 300-150,000Å. |
