Abstract
Intermediate addition of reductant (C 2 H 4 ) into an NO+O 2 stream between an oxidation catalyst for NO to NO 2 (Pt-MFI) and a reduction catalyst for NO x to N 2 (In-MFI), a so-called IAR method, is shown to be very effective in selectively reducing NO to N 2 in the presence of excess oxygen.Keywords
