1、万方数据介质阻挡放电反应器降解甲苯及其结构优化研究复旦大学硕士论文从降解产物来看，催化管不会产生硝基化合物，副产物的种类和产生量也相对较少，初步看来适合工业推广。在绝对湿度为O．4％，初始浓度为208mg／m3的条件下，面．面催化管的甲苯降解率高达88．6％，能耗仅为187kWh／kg。(5)比较相同初始浓度下排管式反应器和套管式反应器的甲苯降解率和能耗发现，两种类型反应器的降解率差异不大。排管式反应器在能处理大通风量有机污染物的同时，又能维持相对较低的能耗，值得工业推广。另外，排管式反应器降解甲

2、苯的副产物少，副产物含量较低，初步看来能较好的解决套管式反应器结焦严重的I'口-J题。在外施电压为10800V，流速为2m／s，初始浓度为270mg／m3的条件下，套管式反应器和排管式反应器的降解率分别为57．4％和59．0％，对应的能耗分别193kWh／kg和251kWh／kg。关键词：甲苯，介质阻挡放电，降解率，能耗结构优化II万方数据介质阻挡放电反应器降解甲苯及其结构优化研究复旦大学硕士论文AbstractAsoneofthemostimportantformerbodyofPM2．5，Ph
