초록
The reaction mechanism of methane dry reforming has been investigated using an arc-jet reactor. The effects of input power, CO2/CH4 and added O2 were investigated by product analysis, including CO, H2, C2HY and C3HY as well as CH4 and CO2. In the process, input electrical power activated the reactions between CH4 and CO2 significantly. The increased feed ratio of the CO2 to CH4 in the dry reforming does not affect to the CH4 conversion. but we could observe increase in CO selectivity together with decreasing H2 generation. Added oxygen can also increase not only CO selectivity but also CH4 conversion. However, hydrogen selectivity was decreased significantly due to a increased H2O formation.
