General of Graphite Nanofibers via the Catalytic Conversion of Methane

65020 Although there is an abundant supply of methane, the costs of transporting it are very high since it requires cryogenic conditions to liquefy the gas. Tremendous benefits could be derived if it were possible to convert the gas to a value added product and at the same time generate hydrogen during the process. Incorporating the products into more efficient systems for electricity generation would be an additional benefit. Although methane is a very stable molecule, transformation is usually achieved via a catalytic route. Therefore, this project will utilize a catalytic approach for the conversion of methane into a high-tech material, graphite nanofibers. Phase I involves (1) the catalytic conversion of methane via partial oxidation into a mixture of CO and H2, and (2) the subsequent decomposition of this mixture to produce tailored carbon nanostructures that can be used in fuel cell applications. Various catalysts will be evaluated in order to ascertain the most efficient and economical system. Commercial Applications and Other Benefits as described by awardee: Rather than burning natural gas in a wasteful manner, its conversion into graphics nanofibers should find use in the efficient and clean generation of electricity, contributing to the reduction of US dependence on foreign oil.
