Claim:
1. A hydrotreating catalyst comprising: a porous refractory carrier; one or more compounds selected from the group consisting oxides of elements in Group II, Group III, and Group IV in the periodic table; an active metal component A, an active metal component B, and an active metal component C; and optionally an auxiliary component, wherein the active metal component A is Ni, the active metal component B is one or more metals selected from the group consisting of Group VIII metals other than Ni, the active metal component C is one or more metals selected from the group consisting of Group VIB metals, the auxiliary component is one or more selected from the group consisting of fluorine, silicon, phosphorus, titanium, zirconium, and boron, wherein the hydrotreating catalyst is in a form of catalyst particles, wherein C when a length of a line segment connecting P C C C C wherein M stands for the active metal component A, the active metal component B, or the active metal component C, wherein a distribution of the active metal component A satisfies Conditions (I) or (II), Condition (I): the active metal component A is substantially uniformly distributed throughout the catalyst particle, Condition (II): the distribution of the active metal component A simultaneously satisfies Formulas (1) and (2): wherein a distribution of the active metal component B satisfies Conditions (III) or (IV), Condition (III): the active metal component B is substantially uniformly distributed throughout the catalyst particle, Condition (IV): the distribution of the active metal component B simultaneously satisfies Formulas (3) and (4): with the proviso that Conditions (I) and (III) are not simultaneously satisfied.
