Method and apparatus for producing carbon nanotubes

摘要

Production of carbon nanotubes involves thermal decomposition of at least one gaseous hydrocarbon in the presence of a solid catalyst. The catalyst is introduced through an entry airlock maintained under an inert atmosphere, and nanotubes are recovered through an exit airlock, which is swept with a flow of inert gas. An independent claim is also included for a device for preparing carbon nanotubes by using the above method.
