Dry powder injection apparatus, and method for producing single-walled carbon nanotube

The method for continuous synthesis of carbon nano compositions, processes and apparatus are provided. A metal catalyst is prepared to have a small diameter and a narrow particle size distribution, is injected continuously into the reactor as an aerosol. Metal catalyst, carbon (carbon) is supported in a little supported material. Powdered metallic catalyst is disposed in the fluidized bed, it is aerosolized using an inert gas. Powder carried put in the gas, for the synthesis of SWNTs, is injected near the top portion of the vertical reactor.
