Fe-ZSM-5 catalysts were synthesized by hydrothermal method under different levels of iron loading. The result of XRD and TG/DTA showed that Fe-ZSM-5 catalysts were successfully obtained after calcination at 550 ℃. The effects of Si/(Fe+Al) and Fe/Al ratio on the SCR performance of Fe-ZSM-5 catalyst were investigated in a simulated flue gas. When Si/(Fe+Al)=20 and Fe:Al=20 Fe-ZSM-5 catalyst showed excellent catalytic activity. Under the condition of 210 ℃, [NH3]/[NO] of 1.2, [O2] of 6 vol%, [NOx] of 900×10-6, Si/(Fe+Al)=20 and Fe/Al=1, NOx conversion exceeds 98%. Besides, Fe-ZSM-5 catalyst was excellently resistant to SO2 and H2O in the SCR reaction. |
