METHOD FOR SIMULTANEOUSLY PRODUCING CARBON NANOTUBES AND HYDROGEN, AND DEVICE FOR SIMULTANEOUSLY PRODUCING CARBON NANOTUBES AND HYDROGEN

摘要

A method for simultaneously producing carbon nanotubes and hydrogen according to the present invention is a method for simultaneously producing carbon nanotubes and hydrogen, in which using a carbon source containing carbon atoms and hydrogen atoms and being decomposed in a heated state, and a catalyst for producing carbon nanotubes and H 2 from the carbon source, the above carbon nanotubes are synthesized on a support in a heated state, placed in a reactor, and simultaneously, the above H 2 is synthesized from the above carbon source, the method comprising a synthesis step of flowing a source gas comprising the above carbon source over the above support, on which the above catalyst is supported, to synthesize the above carbon nanotubes on the above support and simultaneously synthesize the above H 2 in a gas flow.
