FIELD: chemistry.
SUBSTANCE: invention relates to technology of producing fibrous carbon materials through pyrolysis of aromatic and non-aromatic hydrocarbons. Disclosed method of producing carbon nanotubes involves placing a fine catalyst into a reactor fitted with a heater, blowing with inert gas and heating to pyrolysis temperature. Further, carbon-containing gas is continuously fed and gaseous pyrolysis products are removed through a pipe. At the end of the pyrolysis process, the finished product is cooled. According to the invention, a catalyst in form of pellets is placed in the reactor. After sealing the reactor, the heater is switched on and an inert gas and a carbon-containing gas are blown through a gas-distribution device into the reactor, wherein the catalyst pellets are subjected to an acoustic activator.
EFFECT: invention increases efficiency through sharp increase in mass of the compacted catalyst.
