Plasma jet synthesis of carbon nanostructures and a set-up for its implementation

Parametric investigations of the pyrolysis of soot in the presence of catalysts in a reactor have been carried out using a direct-current divergent anode-channel plasma torch with a power of up to 35 kW. The products of the pyrolysis of soot depending on the composition of the catalysts and the operating parameters have been studied by thermogravimetric analysis, scanning electron microscopy and X-ray diffractometry. The optimum conditions for the production of carbon nanotubes for scaling the synthesis process have been found.
