TL;DR: In this paper, the reduction ratio of the amount of NO reduced to that of ethene consumed, reached 1.9 and was much higher than 1.4 of conventional reduction on Cu-MFI.
Abstract: Intermediate addition of reductant (named an IAR method) into a NO+O2 stream between an oxidation catalyst of NO to NO2 and a reduction catalyst of NOx to N2 has been evidenced to be a very effective method to selectively reduce NO to N2 in the presence of excess oxygen. Here Pt-MFI has been employed as an oxidation catalyst, Na-, Mg-, Ca-, Ba-, Zn-and In-MFI have been examined as the reduction catalysts and the reductant was ethene. The combination of Pt-and Zn-MFI was the most effective. The efficiency of ethene, namely the molar ratio of the amount of NO reduced to that of ethene consumed, reached 1.9 and was much higher than 1.4 of conventional reduction on Cu-MFI.
