摘要(Abstract)：

为了探讨催化剂对低温等离子体转化甲烷制甲醇的影响，将Cu-Zn-Al基催化剂引入介质阻挡放电系统，进行了甲烷等离子体-催化制甲醇的研究，考察了催化剂填装方式、催化剂载体、催化剂助剂对甲醇生成的影响。结果表明，将催化剂负载在堇青石蜂窝陶瓷上（Cu-Zn-Al/HC）的填装方式可获得较好的催化效果；堇青石表面结构对甲醇的生成具有显著影响，将催化剂负载在经酸蚀处理的堇青石蜂窝陶瓷上（Cu-Zn-Al/HC-AE），可使单位能耗甲醇产量提高28%；在催化剂中添加助剂Ce利于甲醇的生成，应用Cu-Zn-Al-Ce/HC-AE催化剂时，单位能耗甲醇最大产量较单纯等离子体体系提高了183.7%。基于等离子体-催化甲烷反应结果和发射光谱原位诊断，推断等离子体与催化剂协同转化甲烷制甲醇反应中甲醇通过自由基反应和费托合成两条途径生成。
