Microscope–ICCD Imaging of an Atmospheric Pressure $\hbox {CH}_{4}$ and $\hbox {CO}_{2}$

Images of plasma generation during dry reforming of methane with carbon dioxide in a dielectric barrier discharge reactor using a microscope-intensified charge-coupled device camera have been taken. Comparisons have been made between plasma generations in the absence of a packing material and with different packing materials, including quartz wool, alumina, and barium titanate inside the discharge gap. It has been found that quartz wool can enhance the intensity of plasma generation, leading to improved reaction performance.
