FIELD: chemistry.
SUBSTANCE: invention relates to the technology of producing porous carbon materials and can be used in producing supported catalysts, catalyst supports for catalytic processes, as well as sorbents for adsorption and electrochemical processes. In the disclosed method of producing a porous carbon support, involving mixing soot and aqueous solution of an organic liquid, drying, thermal treatment in the medium of hydrocarbon gases at temperature 800-1000°C and gas-vapour activation to obtain total pore volume of 0.3-0.9 cm3/g, the organic liquid used is compounds with atomic ratio C:H>1. After drying, further thermal treatment is carried out in a non-oxidising medium at 90-500°C in three steps: 5-10 hours at temperature 90-100°C, 1-3 hours at temperature 150-300°C, and then 1-3 hours at temperature 300-500°C, and activation is carried out until material with ratio of micro- and macro-pore volume from 0.2 to 0.5 is obtained.
EFFECT: obtaining a catalyst with high micropore volume.
