In the present invention, only low-growth carbon nanotubes are selectively separated among solid particles discharged during a reaction and then re-input to a reactor, so that it is possible to improve the quality of a carbon nanotube product to be produced and the productivity of a carbon nanotube production process.

System and method for producing carbon nanotubes

A fluidized bed reactor includes: a reactor body; a dispersion plate mounted within the reactor body to partition the inside of the reactor body in a traverse direction and having a plurality of holes through which a reaction gas passes; a nozzle unit mounted on one surface of the dispersion plate to receive an inert gas from outside the reactor and inject the inert gas so as to crush deposits on the dispersion plate; a sensing unit configured to sense the deposits on the dispersion plate; and a control unit configured to control operation of the nozzle unit according to information sensed in the sensing unit.

Fluidized bed reactor

The present invention relates to a device for drying and collecting a product such as a carbon nanotube pellet or aggregate, which can accelerate solvent evaporation by inserting and dispersing high temperature gas into a drying column as well as by a heat source inside and outside of the column, and can quickly remove the evaporated solvent. Further, the device can be used for drying and collecting processes while minimizing product breakage by regulating the gas flow rate and controlling flow of the product in the column. Thus, the device can be effectively applied to mass production of a carbon nanotube pellet product.

The present invention relates to a method for producing carbon nanostructures using a fluidized bed reactor. According to the method, some of the as-produced carbon nanostructures remain uncollected and are used as fluidic materials to improve the fluidity in the reactor. The method enables the production of carbon nanostructures in a continuous process. In addition, the fluidity of the catalyst and the fluidic materials in the reactor is optimized, making the production of carbon nanostructures efficient.
