摘　　要：针对低温脱硝的技术需求,本文建立了介质阻挡放电(DBD)诱导固定碳基还原床(FCRB)负载锰催化剂的新型原位还原脱硝系统(DBD-Mn/FCRB),与单DBD和DBD-FCRB系统相比,该系统具有最佳的脱硝性能,NO转化率和N_(2)选择性可分别达到90.9%和79.9%。该系统具有较强的抗氧冲击性能和抗水性。此外,结合表面微观特性分析,提出了3种可能的脱硝反应路径。研究结果可为低温脱硝提供参考思路。In response to the technical needs of low-temperature denitrification,a new hybrid system(DBD-Mn/FCRB)with a fixed carbonbased reduction bed(FCRB)loaded with manganese catalysts induced by dielectric barrier discharge(DBD)was established,which has the best denitrification performance compared with the single DBD and DBD-FCRB systems.The NO conversion and N_(2) selectivity of the DBD-Mn/FCRB system reached 90.9%and 79.9%,respectively.The system has strong resistance to oxidation shock and water resistance.In addition,combined with the surface microscopic characteristics,three possible denitrification reaction paths have been proposed.The results of the study can provide reference ideas for low temperature denitrification.
