Abstract:
1. An apparatus for synthesizing carbon nanotubes, the apparatus comprising: a reaction tube that provides a space for synthesizing carbon nanotubes and is formed vertically long; a heating unit that is formed at the outer side of the reaction tube, and heats the reaction tube; a gas-supply unit that sprays reaction gas for synthesizing the carbon nanotubes by reacting with catalysts positioned inside the reaction tube; an exhaustion unit that is connected to the upper portion of the reaction tube, and discharges non-reacted reaction gas for synthesizing the carbon nanotubes; and a blocking unit that is formed inside the reaction tube, discharges only the non-reacted reaction gas for synthesizing the carbon nanotubes to the exhaustion unit, and blocks the discharge of the carbon nanotubes and catalysts, wherein the cross-section of the blocking unit is divided in a plurality of polygon structures, and downward-slanted blocking wings are formed at each divided cell.
