Abstract

Abstract

En 中文
• FB NH3 oxidation sensitive to physicochemical properties of bed materials. • Bed materials promote NH3 conversion in order: Fe2O3>CaO > SiO2>empty bed. • Fe2O3 catalyses NH3 oxidation/dissociation, dissociation dominates above 850 °C. • Fe2O3 promotes NH3 oxidation to near-0 NOx (≥850 °C) via Fe3+/Fe2+ redox cycle. • CaO promotes NH3 oxidation but yields high NO emissions at 750–850 °C.
