In this paper, the reaction kinetics of Ce / β zeolite catalysts was studied, indicating that this series of catalysts have good catalytic activity for the selective reduction of nitrogen oxides. The catalyst is controlled by the adsorption of NO on the active site of oxidation state. Through steady-state and unsteady kinetic tests, the influence of temperature on the reaction was studied, and the relationship between the reaction rate constant and the reaction temperature was measured. The introduction of Ce ions improves the exchange capacity of the solid phase of the catalyst with oxygen, thereby accelerating the regeneration rate of the active sites on the catalyst.
