  • SYSTEM AND METHOD FOR PRODUCING CARBON NANOTUBES
    Publication number: 20220289574
    Abstract: 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.

  • PREPARATION METHOD AND PREPARATION SYSTEM OF CARBON NANOTUBES
    Publication number: 20220203320
    Abstract: 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.
