Abstract: 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.

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.
