Iron-Containing SSZ-39 (AEI) Zeolite: An Active and Stable High-Temperature NH3-SCR Catalyst

[EN] The preparation of the iron-containing SSZ-39 zeolite is described for the first time through two different synthesis methods: post-synthetic cation exchange and one-pot synthesis. The nature and stability of the iron species within the different Fe-SSZ-39 materials have been studied through di...

Sumario:[EN] The preparation of the iron-containing SSZ-39 zeolite is described for the first time through two different synthesis methods: post-synthetic cation exchange and one-pot synthesis. The nature and stability of the iron species within the different Fe-SSZ-39 materials have been studied through different characterization techniques, and their catalytic activity has been evaluated for the selective catalytic reduction (SCR) of NOx with ammonia. The directly synthetized Fe-SSZ-39 performs better for the SCR of NOx with ammonia than other related Fezeolites, particularly at elevated reaction temperatures (above 450 degrees C), and presents improved hydrothermal stability when aged under severe conditions.
