Application of atmospheric pressure non-equilibrium plasma, now exclusively produced by Dielectric Barrier Discharge (DBD), is spreading out into various engineering fields of not only material processing, but also energy and environment due to their special advantages of forming highly reactive plasma at room temperature with simple reactor system under atmospheric pressure. This paper reviews recent development of novel plasma reactors and application to efficient conversion of natural gas into hydrogen and carbon-related materials. We first introduces methane pyrolysis using high temperature arc plasmas followed by plasma assisted partial oxidation of methane using Plasmatron and Grlidarc, which are now recognized as commercially competitive plasma fuel converters. We also introduce low-temperature (300〜500℃) steam reforming of methane using plasma/catalyst hybrid reactor developed in our laboratory, which is designed to actively utilize low temperature thermal energy wasted from various industries, providing variety of energy utility options. The principle of generation of such plasma source and application to low temperature plasma catalysis of methane will be discussed in detail.
