Effect of Mn and Ce oxides on low-temperature NH3-SCR performance over blast furnace slag-derived zeolite X supported catalysts
Lin Chen,Shan Ren,Yanhua Jiang,Lian Liu,Mingming Wang,Jie Yang,Zhichao Chen,Weizao Liu,Qingcai Liu +8 more
TL;DR: In this paper , the authors investigated low-temperature NH3-SCR performance of several Mn and/or Ce oxides on blast furnace slag-derived (BFS-derived) zeolite X catalysts and found that Mn-Ce/X catalyst had the highest NO conversion of nearly 98% at 250 °C and excellent N2 selectivity of nearly 100% during 75-175 °C.
