METHOD OF OBTAINING CARBON NANOSTRUCTURES (VERSIONS) AND DEVICE FOR ITS REALISATION (VERSIONS) Russian patent published in 2014 - IPC B82B3/00 C23C14/38 

FIELD: chemistry.

SUBSTANCE: invention relates to obtaining carbon nanostructures. In method of obtaining carbon nanostructures, which includes ignition in vacuum chamber of glow discharge under condition of constant electric current, hydrocarbon gas is supplied into near-cathode region of vacuum chamber in discharge channel in axial and tangential way, and hydrocarbon gas processing is performed under certain parameters of glow discharge. In the second version of the method mixture of inert gas with carbon porder particles is axially supplied into near-cathode region of vacuum chamber into discharge channel with supply of inert gas in tangential way. In device for obtaining carbon nanostructures, containing vacuum chamber with placed in it electrodes, direct current power supply unit, connected to anode and cathode, vacuum chamber has first tangential inlets into near-cathode region for hydrocarbon gas supply and second axial inlet from the cathode side for hydrocarbon gas supply, with electrodes being placed at R=20÷100 mm distance from each other in vacuum chamber. In the second version of device, vacuum chamber has first tangential inlets into near-cathode region for inert gas supply, and second axial inlet from the cathode side for supply of inert gas mixture with carbon powder particles.

EFFECT: invention makes it possible to obtain carbon particles in form of powder, which considerably extends their application, to simplify device and method for obtaining carbon nanostructures, as well as to increase coefficient of efficiency.
