Abstract

Carbon dioxide reforming of methane has drawn the attention of many researchers for years, because of both its theoretical yield of hydrogen to carbon monoxide, i.e., H2CO = 1, and the use of greenhouse gas CO2. Although catalytic processes have been widely investigated, plasma-based techniques were recently considered, because catalytic processes have problems, such as coking and slow start-up time. However, since there is a lack of concrete information about plasma-induced processes, we systematically tested a dry reforming of methane by using an arc-jet plasma reactor. The effects of supplied power for plasma generation, CO2 CH4 ratio, O2 addition, and the amount of CH4} + CO 2 in the reactant were experimentally investigated in nitrogen balance. As a result, the H2CO ratio of a product can be controlled in the range of 0.82.5, and the direction for efficient use of the dry reforming process was proposed. Detailed mechanism and characteristics of the dry reforming of methane were also discussed.
