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

摘要

Disclosed is a method for simultaneously producing carbon nanotubes and hydrogen, comprising: using a carbon source, which contains carbon atoms and hydrogen atoms and is decomposed in a heated state, and a catalyst for generating carbon nanotubes and H2 from said carbon source; synthesizing said carbon nanotubes on a support in a heated state, said support being located in a reactor; and simultaneously synthesizing H2 from said carbon source, characterized by involving a synthesis step for circulating a starting material gas containing said carbon source on said support, on which said catalyst is loaded, to thereby synthesize said carbon nanotubes on said support and simultaneously synthesizing H2 in the gas stream.
