Method and apparatus for generating a carbon nanotube

An apparatus of generating a CNT, comprising:

• a process chamber;
• a catalyst supplier that supplies a catalyst powder into the process chamber in a first direction, the catalyst powder moving in a first direction in the process chamber;
• and
• a source gas supplier that supplies a source gas into the process chamber in a second direction opposite to the first direction, so that the source gas delays the movement of the catalyst powder in the first direction and is reacted with the catalyst powder in the process chamber to thereby produce the CNT in the process chamber,
• wherein the source gas supplier includes:
• a gas reservoir in which the source gas is stored;
• a supply pipe that is connected with both of the gas reservoir and the process chamber;
• a control valve that is arranged at the supply pipe and controls an amount of the source gas supplied into the process chamber through the supply pipe;
• and
• a dispersion plate that is positioned at a lower portion of the process chamber and has a plurality of spray holes, so that the source gas is dispersively supplied into the process chamber through the spray holes and moves upward in the second direction in the process chamber;
• wherein the size of the dispersion plate is substantially smaller than that of the process chamber and the dispersion plate is positioned at a central portion of the process chamber spaced apart from a sidewall of the process chamber by a distance.
