  • Device and method for single-stage continuous preparation of carbon nanotubes
    Patent number: 11820661
    Abstract: An apparatus for continuous preparation of carbon nanotubes, based on a fluidized bed reactor. The fluidized bed reactor comprises an annular varying diameter zone, a raw material gas inlet, a catalyst feeding port, a protective gas inlet, and a pulse gas controller. The annular varying diameter zone is located at a zone from a ¼ position starting from the bottom to the top. The pulse gas controller is disposed at the arc-shaped top portion of the annular varying diameter zone. The catalyst feeding port is located at the top of the fluidized bed reactor. The raw material gas inlet and the protective gas inlet are located at the bottom of the fluidized bed reactor. The device is also provided with a product outlet and a tail gas outlet.
