摘    要:在常温常压下,利用脉冲电晕等离子体研究了甲烷和二氧化碳的转化。在等离子体一催化反应装置上,测试了Pd/γ-Al2O3对甲烷偶联的催化活性。实验发现,在脉冲电晕等离子体作用下,甲烷和二氧化碳被转化为C2烃、CO、H2、O2、少量积碳和高碳烃;在等离子体条件下引入Pd/γ-Al2O3催化剂,能够有效地改善甲烷偶联产物C2烃的分布,有利于生成更高附加值的乙烯。

关 键 词:脉冲电晕等离子体  甲烷  二氧化碳  脱氢偶联  Pd/γ-Al_2O_3  催化

Abstract:At atmospheric pressure and ambient temperature, the dehydrogenation coupling reaction of methane in the precence of carbon dioxide were performed under pulse corona plasma. The effect of addition of Pd/r-Al2O3 as a catalyst were tested on the reaction. It was found that methane and carbon dioxide converted into C2 hydrocarbons, CO, H2, O2, a little carbon and a tittle high hydrocarbons, the addition of Pd/r-Al2O3 catalyst could improve efficaciously the distribution of C2 products.
Keywords:plasma  pulse corona  methane  dehydrogenation coupling  carbon dioxide  palladium
