    Summary
    Summary: Fe-ZSM5 coated on a cordierite monolith was characterized and tested in the selective reduction of nitrogen oxides (NOx) with ammonia. More than 70 % of the NOxwere converted at T>350 °C if only NO was present in the feed. For equimolar amounts of NO and NO2in the feed, NOxconversions of over 90 % were reached for T = 200-450 °C. Hydrothermal ageing of Fe-ZSM5 resulted in a small loss in NOxconversion and enhanced N2O formation
