SUBSTANCE: invention relates to the hydrocarbon oil products hydrogenation catalyst carrier, comprising the said carrier catalyst, carrier production processes, and the catalyst production method. Catalyst carrier contains the oxide-alumina composite oxide, in which obtained by means of the infrared spectrometer with the transmissive type (FT-IR) Fourier transformation the acid OH group absorption band (OH_AS) per carrier surface area unit is in the range from 0.04 to 0.1 m^-2, absorption band (OH_VS) from the main OH groups per carrier surface area unit, obtained with the help of FT-IR, is in the range from 0.01 to 0.02 m^-2 and the acid OH group absorption peak position wave number is in the range from 3670 to 3695 cm^-1, and the main OH group maximum absorption peak position wave number is in the range from 3760 to 3780 cm^-1. Carrier production method comprises: step A of the suspension preparation, in which solution A in the form of alkali metal aluminate aqueous solution is mixed with solution B in the form of aluminum salt aqueous solution and metal salt aqueous solution mixed solution for the first oxide to produce the composite oxide hydrogel suspension (hydrate); and the metal salt addition for the second oxide during or after the above step. Another carrier production method comprises: step B of the suspension preparation, in which solution A in the form of alkali metal aluminate aqueous solution is mixed with solution C in the form of aluminum salt aqueous solution and metal salt aqueous solution mixed solution for the second oxide to produce the composite oxide hydrogel suspension (hydrate); and the metal salt addition for the first oxide during or after the above step. Catalyst comprises: the said carrier and at least one element selected from the periodic table VIA group, and at least one element selected from the periodic table Group VIII, which are been applied to this carrier by the impregnation method.

EFFECT: technical result is increase in the catalyst activity.
