METHOD OF PRODUCTION OF CARBON NANOTUBES AND REACTOR FOR THEIR PRODUCTION Russian patent published in 2013 - IPC C01B31/02 B82B3/00 B82Y40/00 

FIELD: nanotechnology.

SUBSTANCE: invention can be used in the chemical industry. In a reactor comprising a housing 1 on which outer side the heating elements 2 and the thermal insulation are located, the solid particulate catalyst is charged. The catalyst particles at a temperature of catalytic pyrolysis are brought in contact with the gas - the carbon source supplied through the tube 7 or several pipes. In the reactor gas medium, the axisymmetric or circular acoustic waves with a resonant frequency of natural oscillations of the gas or gas-powder mass are excited. Acoustic vibration transmitter can be made in the form of an acoustic horn 8 connected by the tube 7 to the lower part of the reactor. The exhaust gas is discharged from the reactor through the upper tube 3, and the resulting carbon nanotubes are discharged through the lower tube 4 into the hopper 5. During the growth of carbon nanotubes the tube 4 is covered with the flap 6.

EFFECT: increased productivity, reduced energy costs, intensified process of synthesis of nanotubes.
