在同轴介质阻挡放电反应器中研究了常压下CH 4和CO2的低温转化。对输入功率、停留时间、放电间隙、原料气摩尔比和多级电离设计等主要参数进行了评价，以了解提高温室气体转化率和减少副产物产生的途径。在一定的输入功率下，当CH 4/CO2摩尔比为1时，CH 4和CO2的转化率分别达到0.797和0.527。当此比例为1：5时，甲烷转化率可达0.843，CO和H2的选择性接近100%。多级电离有利于CO2的转化，同时也是提高主产物CO和H2选择性，抑制副产物选择性的有效设计。
Low temperature conversion of CH4and CO2was investigated in a coaxial dielectric barrier discharge reactor at ambient pressure. Main parameters, including the input power, the residence time, the discharge gap, the molar ratio of the feed gases and the multi-stage ionization design were evaluated to understand the ways to improve the conversion of greenhouse gases and reduce the output of by-products. At certain input power, the conversion of CH4and CO2can reach 0.797 and 0.527, respectively, when the molar ratio of CH4/CO2is one. When this ratio was low to 1:5, the conversion of CH4was promoted to 0.843 and the selectivity to CO and H2was almost 100%. The multi-stage ionization favored the conversion of CO2, which would also be an efficient design to promote the selectivity to the main products such as CO and H2and suppress the selectivity to the by-products.
