The impacts of hydrothermal aging on the SCR catalyst functions and NOx conversion in NH3-SCR on Cu-SSZ-13 and Cu-SAPO-34 catalysts are explored. All SCR performance tests and characterization results consistently showed relatively more stable structure as well as redox and acidity functions in Cu-SAPO-34 compared with Cu-SSZ-13.
