简介: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 简介:Fe-ZSM-5 catalysts were synthesized by hydrothermal method under different levels of

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 ℃,
[NH 3 ]/[NO] of 1.2, [O 2 ] 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 SO 2 and H 2 O in the SCR
reaction.详细>
