(Summary description)Under the action of plasma plasma, CH4 and CO2 are the raw material gas to synthesize C2 hydrocarbon reforming reaction: Synthesis of C2 hydrocarbons with CH4 and CO2 as feed gas is a very interesting reaction. The first complete reduction product of CO2 hydrogenation is CH4, and the partial reduction product is C2 hydrocarbon; secondly, the complete oxidation product of CH4 is CO2, the partial oxidation product is C2 hydrocarbon, and the intermediate product is CHx. Obviously, these two reactions are mutually reversible. , such as co-activation of CH4 and CO2, that is, the presence of CO2 will be beneficial to the partial oxidation of CH4, and the presence of CH4 will inhibit the deep reduction of CO2, the result of the joint action will be conducive to the formation of C2 hydrocarbons. The significance of studying the CH4 coupling reaction with CO2 as the oxidant is that: first, a method to solve the difficult activation of CH4 is proposed, which provides an effective way to make full use of natural gas: Secondly, the conversion and utilization of CO2 can reduce greenhouse gases to a certain extent. emission. Therefore, this research has important academic value and broad application prospects. The synthesis route of CO2 oxidation of CH4 to C2 hydrocarbons has been reported. Under the action of plasma plasma, CO2 oxidation of CH4 to C2 hydrocarbons can be divided into indirect method and direct method. Synthetic system of C2 hydrocarbons. Zhou et al. used the dielectric barrier discharge method to realize the CO2 reforming CH4 reaction. When the injection energy was 87kW.h/(N∙m3), the conversion rate of methane was 64%, and the conversion rate of carbon dioxide was 54%. Gallon et al. and Pinhao et al. respectively investigated the reforming reaction of CH4 and CO2 under the action of DBD discharge plasma, and the results showed that the main product of the reforming reaction was syngas, and only a small amount of hydrocarbons (mainly C2H6) were generated. However, under the action of DBD discharge plasma, the reactant conversion of CH4 and CO2 reforming reaction is relatively low and the reaction energy consumption is high. Li et al. investigated the reforming reaction of CH4 and CO2 under the action of DC and AC corona discharge respectively. The experimental results show that the reformation reaction of CH4 and CO2 under the action of corona discharge plasma can obtain higher conversion rate of reactants, H2 selectivity and CO selectivity, compared with that obtained by DC positive corona discharge. , followed by AC corona, low DC negative corona. Malik et al. and Gesser et al. realized CO2 reforming CH4 reaction under pulsed corona plasma and silent discharge plasma conditions, respectively. The direct method is to prepare C2 hydrocarbons from CH4 and CO2 in one step, and the reaction can be realized under the action of microwave, flow column discharge and radio frequency plasma. Liu uses the flow column discharge method, with He as the balance gas (accounting for 60%~80% of the total gas flow), under a certain discharge power, according to the different molar ratios of CO2 and CH4, the methane conversion rate is between 20%~80% , the conversion rate of carbon dioxide is between 8% and 49%, and the yield of C2 hydrocarbons is between 20% and 45%. Chen Dongliang et al. directly converted CH4 and CO2 under the action of microwave plasma, and produced C2 hydrocarbons in one step. The main C hydrocarbon products in the reaction were C2H2 and C2H6. The increase of plasma power is conducive to the generation of C2H2. Yao et al. used radio frequency plasma to realize the reaction of CO2 oxidation of CH to C2 hydrocarbons, the methane conversion rate was 31%, the carbon dioxide conversion rate was 24%, and the C2 hydrocarbon selectivity was 64%.
