新型Mn-Fe/ZSM-5催化剂的NH3-SCR脱硝性能
De-NOxPerformance of Novel Mn-Fe/ZSM-5 Catalysts for NH3-SCR
摘要
Abstract
Mn-Fe/ZSM-5 catalyst was prepared by ammonia precipitation-chemical vapor dep-osition method and its performance of the selective catalytic reduction of NO by NH3(NH3-SCR) was investigated.Mn-Fe/ZSM-5 catalyst had better low temperature SCR activity and wider ac-tivity temperature range.NO conversion on it was up to 98% at 180~450 ℃.Meanwhile,this catalyst had better dispersity,higher ability of redox,more appropriate acidity and better resist-ance to SO2.The active components Mn and Fe over Mn-Fe/ZSM-5 catalyst had a synergetic in-teraction.In presence of SO2,Mn-Fe/ZSM-5 catalyst exhibited an excellent resisitance to SO2 with a NO conversion of above 98% at 240~450 ℃.关键词
