Abstract

L'invention concerne un procédé de préparation d'un catalyseur à base de zéolithe de type structural AFX et d'au moins un métal de transition comprenant au moins les étapes suivantes : i) mélange en milieu aqueux, d'au moins deux zéolithes de type structural FAU, d'un composé organique azoté R, d'au moins une source d'au moins un métal alcalin et/ou alcalino-terreux M jusqu'à l'obtention d'un gel précurseur homogène; ii) traitement hydrothermal dudit gel précurseur pour obtenir une phase solide cristallisée, dite « solide » ;iii) au moins un échange ionique avec un métal de transition, iv) traitement thermique. L'invention concerne également le catalyseur susceptible d'être obtenu ou directement obtenu par le procédé et son utilisation pour la réduction sélective de NOx.The invention relates to a process for preparing a catalyst based on an AFX-structured zeolite and on at least one transition metal comprising at least the following stages: i) mixing in aqueous medium, at least two zeolites of structural type FAU, of a nitrogenous organic compound R, of at least one source of at least one alkali metal and / or alkaline earth metal M until a homogeneous precursor gel is obtained; ii) hydrothermal treatment of said precursor gel to obtain a crystallized solid phase, called “solid”, iii) at least one ion exchange with a transition metal, iv) heat treatment. The invention also relates to the catalyst obtainable or directly obtained by the process and its use for the selective reduction of NOx.
