The Effect of Biofuel Originated Potassium and Sodium on the NH3-SCR Activity of Fe–ZSM-5 and W–ZSM-5 Catalysts

The effect of potassium, sodium and water on Fe–ZSM-5, W–ZSM-5 and ZSM-5 catalysts was investigated. Catalysts were characterized by several techniques and tested in the NH 3 -SCR reaction. The impact of water-, K- and Na-treatments on the activity of catalysts was negligible. Thus, the catalysts ca...

Zusammenfassung:The effect of potassium, sodium and water on Fe–ZSM-5, W–ZSM-5 and ZSM-5 catalysts was investigated. Catalysts were characterized by several techniques and tested in the NH 3 -SCR reaction. The impact of water-, K- and Na-treatments on the activity of catalysts was negligible. Thus, the catalysts can be concluded to be resistant to K- and Na-treatments.
