METHOD OF PRODUCING CARBON NANOTUBES IN SUPERSONIC FLOW AND APPARATUS FOR IMPLEMENTING THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: mixture is prepared in a 8 mixer-gas generator by feeding carbon and/or carbon-containing compounds therein from the 15 block, catalyst powder from the 16 block, inert gas from the 6 system through the 7 flow-meter and hydrogen preheated in the 17 apparatus from the 18 source. Connection of the mentioned elements is carried out using 14 software-switching apparatus (SSA). The obtained mixture is fed to the 2 heating system comprising a 1 discharge chamber which is placed inside a 3 radiotransparent tube positioned in the 4 inductor formed in the shape of a spiral, connected to a 5 high-frequency generator. 14 SSA comprises 19 impulse laser which 20 beam, focused on the surface of the 21 metal bar, initiates discharge in the obtained mixture. Induction heating products are directied into the 9 collecting tank through a nozzle cluster containing 13 Laval nozzle with 1.5÷5 Mach numbers. 10 particulate trap cooled by 11 system is positioned in the 9 storage container, which is tightly connected to the 2 heating system and to the 12 inert gas venting system.;EFFECT: increased content of carbon nanotubes in the obtained soot.;2 cl, 1 dwg
