O3-assisted NH3-SCR over FeBEA catalyst at low reaction temperature

[Display omitted] The injection of O3 upstream to the SCR catalyst, FeBEA zeolite, significantly improves its catalytic performance at 100–200 °C. This improvement is due to the oxidation of NO by O3, which proceeds even at ambient temperature, and to the further reduction of the NO + NO2 mixture as...

Summary:[Display omitted] The injection of O3 upstream to the SCR catalyst, FeBEA zeolite, significantly improves its catalytic performance at 100–200 °C. This improvement is due to the oxidation of NO by O3, which proceeds even at ambient temperature, and to the further reduction of the NO + NO2 mixture as a result of fast SCR, NO2-SCR and accumulation of NH4NO3 on the catalyst surface.
