FIELD: chemistry.
SUBSTANCE: invention can find application in the manufacture of catalysts for various branches of the chemical and petrochemical industries, the invention specifically relates to a method of producing alumina carrier for a catalyst comprising the hydrothermal treatment of powdered metallic aluminium in a ratio of Al:H2O=1:8-40 and the drying of hydrothermal synthesis products. The powdered metallic aluminium is used with a particle size of 10-500 nm, the hydrothermal treatment is carried out in one step at a low temperature of 20÷100°C for no longer than 20 minutes without preliminary preparation of materials and without using autoclave equipment. The alumina carrier comprises metallic aluminium in an amount of 5.2 wt %, has a surface area of 178-328 m2/G, a pore volume of 0.53-0.78 cm3/G, an average pore size of 8.6-14.8 nm.
EFFECT: simplification of the method of producing alumina carrier suitable for synthesis of catalytic materials on basis thereof with minimum labour and energy input.
