FIELD: chemistry. n SUBSTANCE: method of producing a carrier containing, wt %: aluminium borate Al 3 BO 6 with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; -γ-Al 2 O 3 - the rest, while aluminium borate Al 3 BO 6 with the structure of norbergite is a particle with dimensions of 10 to 200 nm, characterized by interplanar distances of 3.2 and 2.8 A, with an angle between them of 53.8°. The carrier has a specific surface area of 200-280 m 2 /g, a pore volume of 0.6-0.8 cm 3 /g, the average pore diameter is 7-12 nm and is a particle with a section in the form of a circle, trefoil, or quatrefoil with a diameter of the circumscribed circle of 1.0-1.6 mm and a length of up to 20 mm. n EFFECT: increasing the catalytic activity during hydrotreating of hydrocarbon feedstock. n 3 cl, 2 dwg, 1 tbl, 7 ex |
