Abstract:
The present invention relates to a supported catalyst that can be used to produce a carbon nanotube aggregate with high bulk density, a method for preparing the supported catalyst, a carbon nanotube aggregate produced using the supported catalyst, and a method for producing the carbon nanotube aggregate. According to the present invention, the bulk density of the carbon nanotube aggregate is easily controllable. Therefore, the carbon nanotube aggregate is suitable for use in various fields.
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.
