Abstract: An apparatus and method for manufacturing a carbonaceous material are provided. The carbonaceous material manufacturing apparatus includes a reaction tube and a gas supply portion. An anode and a cathode defining an arc discharge portion is placed in the reaction tube, and a capturer is located provided as well to capture carbonaceous materials generated. At the location of the capturer, an RF heater is disposed around the reaction tube. In a carbonaceous material manufacturing method, carbonaceous materials generated in the arc discharge portion are transported from a gas supply portion into the reaction tube by the gas supplied into the reaction tube, then heated by a RF heater in the capturer where the carbonaceous materials are not exposed to the atmospheric air, to thereby promote removal of impurities and growth of single-walled carbon nanotubes.
