Résumé

Cu-ZSM-5 NO-SCR-C10H22 catalyst deactivation hydrothermal treatment
The steam treatment of Cu-ZSM-5 prepared by solid ion exchange involves an important decrease of the NO conversion. Characterization of the solids by NOTPD, H2-TPR, 27Al MAS NMR shows that the catalyst deactivation is mainly due to change in copper species rather than the collapse of the zeolite framework.
