The objective of this paper is to investigate the improvement effect on the NOx conversion of different additives into the Cu based SCR/CDPF catalyst. The catalysts used in this test were Cu-BEA( is simplified by just writing Cu in the latter) ,CuCe, CuNb and CuCeNb. Under standard SCR reaction, NOx conversions of catalysts that had added additives were all higher than the Cu catalyst. CuCeNb catalyst had the highest NOx conversion among the three kinds catalysts. . NOx conversions of all the catalysts were improved about 20% in fast SCR reaction and the CuCeNb catalyst still showed the highest NOx conversion. These results show that the additives of Ce and Nb can both improve the NOx reduction performance of the Cu based SCR/CDPF catalyst and the improvement was enhanced when both Ce and Nb were added. |
