(Summary description)CH4 and CO2 reforming reaction under the combined action of DBD plasma and catalyst: The conversion reaction of CO2 oxidation to CH4 under the action of plasma is mainly initiated by free radicals, and the target product C2 hydrocarbon has poor selectivity. The CO2 oxidation CH4 conversion reaction under chemical catalysis has higher selectivity of the target product. For example, the target product given by the supported nickel catalyst is syngas (CO+H2); the target product using lanthanide oxides as the catalyst is a C2 hydrocarbon. In the catalytic reaction, due to the high energy required to break the C-H bond of methane and the C-O bond of CO2, the synthetic route using C2 hydrocarbons as the target product has disadvantages such as high reaction temperature and low conversion rate of CH4. Wang et al. investigated the CH4 and CO2 reforming reaction under the combined action of DBD plasma and catalyst. The results show that the synergistic effect of the two can effectively improve the conversion rate of reactants and the selectivity of target products. Some research groups have also investigated the reforming reaction of CH4 and CO2 under the conditions of sliding arc discharge combined with catalyst, and the experimental results all show that the synergistic effect of the two is obvious. The plasma-catalytic co-activation method is used to promote the conversion of methane into the target product C2 hydrocarbons. Although the heterogeneous catalysis of plasma may occur in the plasma area, plasma afterglow area and product collection area, because the pulsed corona plasma works under normal pressure, the particle density in the system is high and the collision probability is high, so The active particles such as free radicals have extremely short lifetimes, and the heterogeneous catalysis that occurs in the plasma region is mainly studied.
