FIELD: chemistry. n SUBSTANCE: invention relates to catalysis and specifically to catalytic cracking gasoline hydrotreating catalysts to obtain a commercial grade gasoline component with low sulfur content with minimum octane reduction and can be used in petroleum refining industry. Described is a catalyst which contains cobalt, molybdenum and a carrier containing, wt%: [Co(H 2 O) 2 (C 6 H 5 O 7 )] 2 [Mo 4 O 11 (C 6 H 5 O 7 ) 2 ] – 17.4-27.4 %; carrier – balance; wherein the carrier contains, wt%: aluminum borate Al 3 VO 6 with norbergite structure – 5.0-25.0; sodium – not more than 0.03; amorphous aluminum silicate – 30–50; γ-Al 2 O 3 – balance. Amorphous aluminosilicate, which is part of the catalyst, contains silicon and aluminum in weight ratio of 0.2 to 0.3. n EFFECT: high hydrodesulphurisation activity of the catalyst in hydrotreatment of catalytic cracking gasoline, as well as high selectivity of the catalyst, which is expressed in reducing the degree of hydrogenation of olefin hydrocarbons and reducing the value of falling octane number of catalytic cracking gasoline during hydrotreatment. n 1 cl, 1 tbl, 4 ex |
