METHOD OF OBTAINING CARBON NANOTUBES AND REACTOR (VERSIONS) Russian patent published in 2013 - IPC C01B31/02 B82B3/00 B82Y40/00 

FIELD: nanotechnology.

SUBSTANCE: invention can be used in electronics, medicine and chemistry. In the volume of the reaction chambers 412 and 414 the vapors of catalyst material are obtained by evaporation of partially melted electrodes 435 and 445, made in the form of a reservoir filled with a metal containing catalyst. The electric arc discharge 450 is formed between the electrodes 435 and 445 in the discharge channel 405. Through the inlet 418 the plasma-forming gas is fed and in the vortex chamber 405 its vortex flow is obtained. During condensation of the resulting catalyst vapors the nanoparticles of the catalyst are formed, on which gaseous hydrocarbons are decomposed fed through the inlets 432 and 434. The products of decomposition of hydrocarbons in the form of carbon nanotubes, formed on the surface of the nanoparticles of the catalyst, are withdrawn through the outputs 442 and 444. According to another version, the reactor for obtaining carbon nanotubes comprises one reaction chamber and the second electrode may be solid, made of graphite or refractory metal. According to the third version, the reactor for obtaining carbon nanotubes comprises three reaction chambers.

EFFECT: combination of obtaining the catalyst and nanotubes in one reactor exception of complex, expensive and multi-stage process of manufacturing the catalyst.
