Abstract
The inventive method for producing fullerene-containing carbon and the device for carrying out said method relate to the chemical industry and are used for producing fullerenes. Said method for producing fullerene-containing carbon consists in vaporising graphite in an electric arc between coaxial graphite electrodes. The graphite electrode is continuously moved inside the electric arc zone through the glow discharge zone. The products formed inside the electric arc are removed therefrom with the aid of an annular inert gas flow which is directed along the axes of the electrodes through an area arranged at a defined distance from a discharge axis. The inventive device for producing fullerene-containing carbon comprises a plasma reactor provided with a system for circulating inert gas and a system for recuperating fullerene carbon. Said reactor is provided with a chamber for degassing the graphite electrode which is continuously moved by the glow discharge towards the arc. The system for circulating inert gas is provided with an annular slot nozzle coaxially arranged in relation to the moving graphite electrode.
