FIELD: chemistry.

SUBSTANCE: present invention provides for the hydroprocessing catalyst suitable for hydrodesulfurization of the heavy distillate fuel, its preparation (options), and its use. Hydroprocessing catalyst, which is present in the particulate form, includes the porous high-melting medium, the active metal component A, the active metal component B, the active metal component C and optionally the auxiliary component, which are applied to the porous high-melting medium. Active metal component A is Ni. Active metal component B is one or more metals, selected from the group consisting of the non-Ni metals of Group VIII of the Periodic Table of Elements. Active metal component C is one or more metals selected from the group consisting of metals from Group VIB of the Periodic Table of the Elements. Auxiliary component is one or more elements selected from the group, which consists of fluorine, silicon, phosphorus, titanium, zirconium and boron. In the catalyst, the concentration distribution of the active metal component A satisfies the condition (I) or (II). Condition (I): over the entire cross-sectional area of each individual catalyst particle, this concentration is distributed almost uniformly. Condition (II): over the entire cross-sectional area of each individual particle of the catalyst, this concentration simultaneously satisfies the following formulas (1) and (2):

formula (1): C^A_out > C^A_1/4 > C^A_1/2 > C^A_3/4 > 1, formula (2): C^A_out ≥ 1.5. Concentration distribution of the active metal component B satisfies the condition (III) or (IV). Condition (III): over the entire cross-sectional area of each individual catalyst particle, this concentration is distributed almost uniformly. Condition (IV): over the entire cross-sectional area of each individual particle of the catalyst, this concentration simultaneously satisfies the following formulas (3) and (4): formula (3): C^B_out < C^B_1/4 < C^B_1/2 < C^B_3/4 < 1, formula (4): C^B_out ≤ 0.80. Concentration distribution of the active metal component A and the concentration distribution of the active metal component B simultaneously satisfy the conditions (III) and (IV).

EFFECT: this hydroprocessing catalyst exhibits significantly increased activity in respect of (deep) hydrodesulfurization of heavy distillate fuel.
