Kinetics and H₂O Influence on NOx Trapping and Selective Catalytic Reduction over Ce/Pd Doping Catalyst.

ABSTRACT: In this paper, the removal effects and activation energy of Ce and Pd doping on pollutants (CO, C₃H₆, and NO) were comparatively analyzed by using characterization methods and constructed kinetic equations. Furthermore, the problems of the water influence mechanism on the NSR process were also discussed. The results show the following: (1) Pd doping effectively improves the removal of CO (80%) and C₃H₆ (71%) in the low-temperature section of the catalyst (150-250 °C) compared to Ce doping, while Ce doping exhibits excellent low-temperature conversion of NO. (2) The reaction activation energy of the LaKMnPdO₃ catalyst was 9784 kJ/mol, which was significantly lower than that of the LaKMnCeO₃ catalyst. (3) The presence of H
