  • Preparation method and preparation system of carbon nanotubes
    Patent number: 12214343
    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.
    Type: Grant
    Filed: July 29, 2020
    Date of Patent: February 4, 2025
    Assignee: LG CHEM, LTD.
    Inventors: Og Sin Kim, Uk Yeong Kim, Se Hyun Kim, Yon Jee Kim

  • Carbon nanostructure preparation method, carbon nanostructure prepared by means of same, and composite material comprising same
    Patent number: 10457556
    Abstract: 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.
