Patent ID: 7964151

Claim:
An apparatus for producing carbon nanotubes, comprising: a reaction chamber providing a reaction space for forming carbon nanotubes; and a dispersion plate provided on a bottom surface of the reaction chamber, to discharge a source gas in the reaction space for producing the carbon nanotubes, the dispersion plate comprising: a plate defining a catalyst supply hole at a central portion thereof for flowing metal catalysts that react with the source gas and produce carbon nanotubes, the metal catalysts flowing through the catalyst supply hole into the reaction space; and a gas guiding portion provided on an upper surface edge of the plate, to receive and guide the source gas to a central portion of the plate; and wherein the gas guiding portion, together with the plate, defines a gas storing space into which the source gas enters in a first stage, and defines a gas outlet that discharges the source gas that enters the gas storage space toward the central portion of the plate.
