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 from 10 to 200 nm, characterized by interplanar distances of 3.2 and 2.8 Å, 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. The method of producing a carrier includes the following steps: grinding the thermal activation product of hydrargillite (gibbsite) Al(OH) 3 up to particles with an average size of 20-50 mcm; hydrating; washing to a residual sodium content of not more than 0.03 wt %; hydrothermal treating the suspension; spray drying; peptizing; extruding, drying and calcining at a temperature of not more than 600°C. n EFFECT: increasing the catalyst activity in the targeted reactions occurring during the hydrotreatment of hydrocarbon feedstocks. n 10 cl, 1 tbl, 1 dwg, 7 ex |
