Abstract :
In this article it is demonstrated that DBD (dielectric barrier discharge) is an effective tool to convert CH4 and CO2 to synthesis gas (syngas, H2/CO) at low temperature and ambient pressure. The DBD is performed in the co-axial quartz cube by using the high frequency power supply. The dielectric Al2O3 grains are filled in the discharge space to improve the discharge uniformity. The synthesis gas produced in this system can have an arbitrary H2/CO ratio, mainly depending on the mixing ratio of CH4/CO2 in the feed gas. Specific electric energy also influences syngas composition. The amount of syngas produced strongly depends on the electric energy input. The energy consumption of syngas and the reaction process are investigated too.
