Provided is an apparatus for producing carbon nanotubes. The apparatus includes a reaction chamber and a rotating member. The reaction chamber provides a reaction space in which metal catalysts and a source gas react with one another to produce carbon nanotubes. The rotating member increases fluidizing of the metal catalysts in the reaction space to increase productivity and raise the gas conversion rate, thereby reducing the price of carbon nanotubes and preventing adhering of metal catalysts to the sidewall of the reaction chamber.

Provided are an apparatus for synthesizing carbon nanotubes, the apparatus including a reaction tube that provides a space for 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, in which 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.

Apparatus for synthesizing carbon nanotubes

Provided is an apparatus for synthesizing carbon nanotubes (CNTs). The apparatus includes: a vertical reaction chamber; a mixer which is disposed within the vertical reaction chamber and mixes a catalyst supplied from above; and a plurality of dispersion plates which vertically partition a space inside the vertical reaction chamber into a plurality of sections and uniformly disperse a source gas, which is supplied from above, into the sections.

Provided is an apparatus for producing carbon nanotubes, that is provided with a reaction chamber and a dispersion plate. The dispersion plate is provided with a plate and a gas guiding portion provided on an edge of the plate, and a catalyst supply hole is defined in the central portion of the plate, through which metal catalysts are supplied. The gas guiding portion guides source gas to the central portion of the plate and suspends the metal catalysts discharged from the catalyst supply hole in a specific direction. Thus, the apparatus for producing carbon nanotubes can prevent loss of metal catalysts and improve space utilization.
