CATALYST FOR TREATING EXHAUST GAS
Provided is a metal promoted, low SAR zeolite-based SCR catalyst having at least about 1.35 weight percent of cerium, based on the total weight of the zeolite, wherein said cerium is present in a form selected from exchanged cerium ions, monomeric ceria, oligomeric ceria, and combinations thereof, p...

| description | Provided is a metal promoted, low SAR zeolite-based SCR catalyst having at least about 1.35 weight percent of cerium, based on the total weight of the zeolite, wherein said cerium is present in a form selected from exchanged cerium ions, monomeric ceria, oligomeric ceria, and combinations thereof, provided that said oligomeric ceria has a particle size of less than 5 μm, the catalyst having superior durability after hydrothermal aging. |
