CA 2612310

The present invention concerns a process for producing carbon nanotubes or other carbon nanostructures, e.g. cones. The process comprising evaporating/decomposing a carbon containing material in a voluminous thermal plasma generated by rotating an electric arc using an externally applied magnetic field, and condensing said evaporated/decomposed carbon containing material on surfaces or on particles in a gas flow. A reactor for performing the process is also described.

La présente invention concerne un procédé de production de nanotubes de carbone ou autres nanostructures de carbone, telles que des cônes. Le procédé consiste à évaporer/décomposer un matériau contenant du carbone en un plasma thermique volumineux généré par rotation d'un arc électrique utilisant un champ magnétique à application externe, et à condenser le matériau contenant le carbone évaporé/décomposé sur des surfaces ou sur des particules dans un écoulement gazeux. L'invention concerne également un réacteur destiné à être utilisé dans ce procédé.
