FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst, methods for its production and to a method for hydrotreatment of hydrocarbon raw materials in its presence. The catalyst for the hydrotreatment of hydrocarbon raw materials, after its transformation into a sulfidated form, contains at least one component of group VIB metal, which is molybdenum, at least one component of group VIII metal selected from nickel and cobalt, at least one organic additive, a phosphorus component in the amount of at least about 1% by wt. per P₂O₅ oxide, per the total weight of the catalyst, and a component, which is a titanium-containing carrier containing aluminum oxide, which does not necessarily contain silicon dioxide. The amount of the titanium component is in the range of 5-50% by wt. per TiO₂ oxide and per the total weight of the catalyst. The catalyst contains silicon dioxide in the amount that is less than 1.0% by wt. per SiO₂ oxide and per the total weight of the catalyst. An organic additive is an organic compound selected from a group consisting of organic compounds containing at least two oxygen atoms and 2-10 carbon atoms, and esters formed from them, or an organic additive is mercaptocarboxylic acid. A method for producing a catalyst intended for subsequent conversion to a sulfidated form includes co-extrusion of a titanium source with porous material containing Al₂O₃ to form an extrudate of a titanium-containing carrier containing aluminum oxide, which optionally contains silicon dioxide, drying and calcining the extrudate and impregnating the calcined extrudate with an organic additive, at least a molybdenum metal source and at least one nickel and/or cobalt metal source. The extrudate can also be obtained by deposition of a titanium source with an aluminum source and extrusion of the precipitate. Alternatively, the carrier can be obtained by impregnating porous material containing Al₂O₃ with a titanium source, with the formation of a titanium-containing carrier.

EFFECT: production of hydrotreatment catalysts with increased volumetric activity or catalysts with high activity at significantly lower concentrations of active components of group VIB and group VIII metals.
