Low-density carbon nanotubes may be prepared using a fluidized bed reactor provided with a side nozzle, and are excellent in electrical properties and appearance characteristics when used as a composite material.

Carbon nanotube having low density and composite material including the same

The present invention relates to a carbon nanotube preparation method and system, which may improve the overall efficiency and economic feasibility of a reaction by collecting fine particles including carbon nanotube particles that have not grown enough and an unreacted catalyst produced during and after the reaction by using a separator at the exterior of a fluidized bed reactor, and then, injecting the fine particles as a bed prior to a subsequent cycle.

Preparation method and preparation system of carbon nanotubes

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

The present invention relates to entangled-type carbon nanotubes which have a bulk density of 31 kg/mto 85 kg/mand a ratio of tapped bulk density to bulk density of 1.37 to 2.05, and a method for preparing the entangled-type carbon nanotubes.

Entangled-type carbon nanotubes and method for preparing the same

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.
