Abstract
Official abstract text for this publication.
The method for producing carbon nanotubes employs a carbon source that contains carbon and is decomposed when heated and a catalyst on a support that serves as a catalyst for production of carbon nanotubes from the carbon source. The method includes a catalyst loading step in which the catalyst starting material is distributed over the support to load the catalyst onto the support, a synthesis step in which the carbon nanotubes are synthesized 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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: a catalyst loading step in which the catalyst starting material, as the starting material for the catalyst, is distributed over the s…
