Abstract: A reaction assembly has an elongate vessel defining a reaction chamber. Planar supports within the reaction chamber have surfaces for supporting a solid catalyst. The planar supports are mounted transversely to an elongate axis of the vessel, forming a series of spaced-apart barriers. A conduit introduces gas through openings between successive barriers such that gas flow through the conduit causes gas to flow along the support surfaces. With selection of an appropriate metal nanoparticle catalyst that may be seeded on the support surfaces. the reaction assembly may be used to produce carbon nanofibers from carbon monoxide and hydrogen, wherein the nanofibers may be subsequently removed via injection of a fluid.

Abstract: A process and apparatus for producing carbon nanofibers. The process comprises two stages. The first stage involves oxidizing light hydrocarbon with carbon dioxide or water, or oxygen, or a combination thereof to a mixture of hydrogen and carbon monoxide. The second stage involves converting the produced hydrogen and the carbon monoxide to carbon nanofibers and steam. In this way, greenhouse gases may be reduced by using carbon dioxide and methane (and/or other light hydrocarbons) as reactants; and useful products may be produced, such as Carbon NanoFibers (CNF).
