Abstract

The kinetics of catalytic decomposition of NO over Cu/ZSM-5 catalyst has been studied in an integral flow reactor at atmospheric pressure. Kinetic analysis is based on the assumption that the surface reaction represents the rate-determining step. On the basis of theoretical considerations of different interactions between reactants and catalyst, and experimental evidences, three different mechanistic kinetic models were chosen. Also a power-law model was tested. The best agreement has been achieved with the model

$$r_S = \frac{{k \cdot C_{NO} ^2 }}{{\left( {1 + \sqrt {K_D ^1 \cdot C_{O_2 } } } \right)^2 }}$$
