METHODS AND REACTORS FOR PRODUCING SOLID CARBON NANOTUBES, SOLID CARBON CLUSTERS, AND FORESTS.

摘要

Methods of producing fibrous solid carbon forests include reacting carbon oxides with gaseous reducing agents in the presence of a catalyst having a predetermined grain size to cause growth of fibrous solid carbon forests upon a surface of the metal. The fibrous solid carbon forests are substantially perpendicular to the surface of the metal thus creating the "forests". A bi-modal forest composition of matter is described in which a primary distribution of fibrous solid carbon comprises the forest and a secondary distribution of fibrous solid carbon is entangled with the primary distribution. A reactor includes a catalyst, a means for facilitating the reduction of a carbon oxide to form solid carbon forests on a surface of the catalyst, and a means for removing the solid carbon forest from the surface of the metal catalyst.
