Abstract
Catalytic activity of CuMOR catalysts for NO selective catalytic reduc tion by propene was investigated as a function of the cocation (H, Na, Cs, Mg and Ba) present in the zeolite. It was verified that the cocat ion plays an important role in the CuMOR activity, its effect being mo re pronounced at low temperatures. Moreover, the results suggest that we can prevent the catalyst deactivation by choosing the appropriate c ocation.
