Progress of non-thermal plasma reactors for oxidative reforming of hydrocarbon fuel

Oxidative reforming (partial oxidation) of fuel is mildly exothermic and has the advantages of fast reaction and low energy cost, which is especially suitable for on-line production of H₂ or H₂-rich gas. Atmospheric-pressure non-thermal plasma provides a very promising new technology for oxidative reforming of fuel with significant advantages of feed flexibility, fast response, and compact, efficient reactor. The recent developments of atmospheric pressure non-thermal plasma reactors for oxidative reforming of hydrocarbon fuel are reviewed. The warm plasma generated by spark and gliding arc discharges and its fuel reforming reactors are presented. Compared with the reactors of cold plasma generated by corona and dielectric barrier discharges, the warm plasma reactor exhibits high fuel conversion as well as low energy cost.
