摘要(Abstract)：

采用一段式介质阻挡放电催化反应系统,对模拟柴油车发动机尾气中的碳氢化合物(正葵烷,C10)进行处理。研究了C10在不同贵金属催化剂作用下的去除差异性,探讨了催化剂负载量、C10初始浓度、反应温度、能量密度对等离子体贵金属催化去除C10的影响。结果表明:与单独等离子体或热催化相比,等离子体催化能够显著提高C10去除率,等离子体和催化的协同作用显著。Pt/Al_2O_3的催化效果优于Pd/Al_2O_3、Ag/Al_2O_3,其不仅转化率高,而且促进了CO氧化生成CO_2。增加催化剂负载量、能量密度和反应温度都有利于提高C10去除率和CO、CO_2选择性,实验中C10去除率可达91%,CO和CO_2总选择性最大为54.3%,而初始浓度的增加则不利于C10去除。

关键词(KeyWords)： 介质阻挡放电;贵金属催化剂;C10;去除率;COx选择性
