摘要(Abstract)：

非平衡等离子体重整CO_2-CH_4制合成气是实现2种温室气体资源化利用的新兴技术途径。综合采用发射光谱分析、反应动力学计算和连续质谱对常温常压介质阻挡放电(DBD)非热等离子体重整CO_2-CH_4反应途径进行探索。比功率S_(EI)为52 J/cm~3时，可得到CH_4和CO_2转化率最大分别为22.8%和9.4%。稳态气相产物连续质谱在线分析表明，C_2H_4为C_2烃生成重要中间体，CH_4比例越高C_2烃生成量越大，且按C_2H_6CO_2-CH_4 reforming by non-equilibrium plasma to syngas is an important emerging technology pathway to realize the resource utilization for the two greenhouse gases. The reaction pathway of CO_2-CH_4 reforming by non-thermal plasma in a dielectric barrier discharge(DBD) reactor at ambient temperature and pressure was thoroughly investigated by combing emission spectrometry analysis, reaction kinetics simulation and continuous mass spectrometry measurements. A maximum conversion of CH_4 and CO_2 of 25.8% and 9.6% respectively, can be achieved under a specific energy input(S_(EI)) of 52 J/cm~3. The continuous mass spectrometry online analysis of the stable gaseous products shows that C_2H_4 acts as a key intermediate in the formation of C_(2 )hydrocarbons. The higher the proportion of CH_4, the greater the generation of C_2 hydrocarbons, and it increases in the order of C_2H_6
