将介质阻挡放电(DBD)等离子体与Cu-Ni/γ-Al2O3催化剂结合用于甲烷二氧化碳重整制合成气.结果表明:DBD等离子体与催化剂之间产生明显的协同作用,与单纯放电或是单纯催化相比较,DBD等离子体与催化剂相结合极大地提高了反应活性及稳定性.通过XRD,H2-TPR,XPS及O2-TPO表征发现,Cu与Ni之间存在明显的相互作用,改变了各自的还原性能;同时Cu的加入提高了Ni的分散程度;等离子体的引入减少了反应过程中积炭的形成,提高了反应稳定性. The dielectric barrier discharge (DBD) plasma was used in combination with Cu-Ni / γ-Al2O3 catalyst for methane carbon dioxide reforming syngas. The results show that there is a clear synergy between the DBD plasma and the catalyst, Compared with simple catalytic, the DBD plasma combined with the catalyst greatly enhanced the reactivity and the stability of the catalyst.By XRD, H2-TPR, XPS and O2-TPO characterization, there was a clear interaction between Cu and Ni, which changed The reduction performance of Ni was also improved by the addition of Cu. The introduction of plasma reduced the formation of coke during the reaction and improved the reaction stability.
