摘要
A kinetic model for self-sustained isothermal oscillations occurring during N2O decomposition on Cu-ZSM5 has been developed. The dynamic behaviour has been explained by a reaction mechanism producing periodic changes of the state of oxidation of the catalyst. The oscillations have been simulated by assuming that the solid-solid reaction step exhibits an activation energy proportional to the catalyst reduction degree. (C) 1999 Elsevier Science Ltd.
