“…As examples of non-equilibrium discharge, acetylene production from methane in a DC pulse discharge 72), 73) , and oxidative coupling of methane in a corona discharge 74), 75) were reported. Furthermore, partial oxidation, steam reforming, and dry reforming of methane were investigated in a grid-arc discharge 76) . Our group has also investigated the utilization of non-equilibrium discharge, especially methane activation by non-equilibrium pulse discharge.…”

Direct conversion of methane to other valuable products such as ethylene, methanol, benzene, carbon, hydrogen, and syngas has been widely investigated. Such conversion requires high temperatures because of the strong C-H bond in CH4, and such high-temperature reactions present various problems: sequential reaction to decrease the selectivity to target products, need for multiple heat exchangers to use or recover high-temperature waste heat, materials that are stable at high temperatures, etc. To solve these problems, several trials have been undertaken to lower reaction temperatures using plasma, Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA), and electric fields. This review describes recent trends in methane conversion, and describes our methods to lower the reaction temperature.

“…The limited quantity of excited species produced by the plasma is insufficient to provide energy required for complete reformation of the feed gas resulting in extremely non-uniform gas treatment [17], Equation (1) [19] states a general equation for the reforming of methane. When y equals 0 and x is greater than 0 steam reforming takes place [19] following equation (2) [20]. Partial oxidation occurs when x = 0 and y > 0 yet is less than needed for the combustion of methane (equation 3) [20].…”

Partial oxidation occurs when x = 0 and y > 0 yet is less than needed for the combustion of methane (equation 3) [20]. This paper primarily investigates the partial oxidation of methane in a fuel rich environment, and thus oxygen considered exists in pure form or air and steam is neglected (equation 4) [20].…”

SUPPLEMENTARY NOTES ABSTRACTThis report covers efforts by the Hawaii Natural Energy Institute (HNEI) of the University of Hawaii under the ONR-funded HEET Initiative that addresses critical technology needs for exploration/utilization of seabed methane hydrates, development/testing of advanced fuel cells and fuel cell systems, an expanded effort on fuel processing and purification, and a new task addressing testing and evaluation of alternate energy sources, with initial activities in testing of heat exchangers for ocean thermal energy conversion (OTEC), grid storage, and photovoltaics. In addition to work involving fuel cell testing, HNEI also participated in fuel cell development activities, including efforts in support of biocarbon fuel cells and the development of enzymatic bio-fuel cells.

“…However, generation of high-temperature plasma requires a high level of power consumption. On the other hand, low-temperature plasma such as the Glidarc plasma [6] and the dielectric barrier discharge are being studied [7] at low power and at temperatures lower than a steam reforming with the catalyst required for the high temperature. However, for low-temperature plasma reforming, the low CH 4 conversion rate is a problem.…”

SUMMARYA reformer using low-temperature plasma was designed and developed for hydrogen production. The reformer has three electrodes and uses AC gliding arc discharge.A reference condition, which is the highest hydrogen production, has a O 2 =C ratio of 0.45, input flow rate of 4:9 l min À1 and power supply of 1 kW. And the methane conversion rate, the high hydrogen selectivity and the reformer efficiency were 69.2, 77.8 and 35.2%, respectively.To investigate reforming characteristics, parametric studies were achieved for the gas components ratio, a gas flow rate, a reactor temperature, an input electric power and catalyst addition effect.The results are as follows: The gas components ratio was an important factor, which had maximum value. When the gas flow rate, the reactor temperature and the electric power were increased, the methane conversion rate and the hydrogen concentration also increased.
