Estimating the term…
The method for producing carbon nanotubes of the invention employs a carbon source that contains carbon and is decomposed when heated and a catalyst that serves as a catalyst for production of carbon nanotubes from the carbon source, to synthesize the carbon nanotubes on a heated support placed in a reactor, the method comprising a catalyst loading step in which the catalyst starting material, as the starting material for the catalyst, is distributed over the support to load the catalyst onto the support, a synthesis step in which the carbon source is distributed over the support to synthesize the carbon nanotubes on the support, and a separating step in which a separating gas stream is distributed over the support to separate the carbon nanotubes from the support, wherein the catalyst loading step, the synthesis step and the separating step are carried out while keeping the support in a heated state and switching supply of the catalyst starting material, the carbon source and the separating gas stream.
A method for producing carbon nanotubes wherein a carbon source that contains carbon and is decomposed when heated and a catalyst that serves as a catalyst for production of carbon nanotubes from the carbon source, are used to synthesize the carbon nanotubes on a heated support placed in a reactor, the method comprising:
An apparatus for producing carbon nanotubes wherein a carbon source that contains carbon and is decomposed when heated and a catalyst that serves as a catalyst for production of carbon nanotubes from the carbon source, are used to synthesize the carbon nanotubes on a heated support placed in a reactor,
