ACTIVITY OF ALUMINUM PHOSPHATE-BASED CATALYSTS FOR SELECTIVE CATALYTIC REDUCTION OF NITROGEN MONOXIDE BY ETHENE IN EXCESS OXYGEN

Abstract

The activity of AlPO₄ for C₂H_4-SCR-NO was examined and discussed on the basis of its reaction pathway. The conversion of NO to N₂ in C₂H₄-SCR-NO over AlPO₄ was very low, because of its low NO oxidation ability to form NO₂. Therefore, C₂H_4-SCR-NO over several metal-loaded AlPO₄(M/AlPO₄) was also investigated to achieve higher activity.
