Title (EN) METHOD FOR THE DIRECT SYNTHESIS OF IRON-CONTAINING AEI-ZEOLITE CATALYST
(FR) PROCÉDÉ DE SYNTHÈSE DIRECTE D'UN CATALYSEUR ZÉOLITHE AEI CONTENANT DU FER
Abstract:
(EN) A method for the direct synthesis of a crystalline material with the AEI zeolithic structure containing iron-species and being essentially free of alkali ions, comprising the following steps: (i) preparation of a mixture containing water, a high-silica zeolite as a main source of silica and alumina, an alkyl-substituted cyclic ammonium cation as organic structure directing agent (OSDA), a source of iron, and a source of an alkali metal ion [Alk], to obtain a final synthesis mixture having the following molar composition: SiO2 : a AI2O3 : b Fe : c OSDA : d Alk : e H2O wherein a is in the range from 0.001 to 0.2; wherein b is in the range from 0.001 to 0.2; wherein c is in the range from 0.01 to 2; wherein d is in the range from 0.001 to 2; wherein e is in the range from 1 to 200; (ii) crystallization of the mixture achieved in (i); (iii) recovery of the crystalline material achieved in (ii); (iv) calcination of the crystalline material from step (iii); and (v) removal of the alkali metal cation, present in the calcined crystalline material after step (iv) to obtain a final molar composition: SiO2 : o AI2O3 : p Fe : q Alk wherein o is in the range from 0.001 to 0.2, p is in the range from 0.001 to 0.2 and q is below 0.02.
(FR) La présente invention concerne un procédé de synthèse directe d'une substance cristalline présentant la structure zéolithique AEI contenant des espèces à base de fer et qui est essentiellement exempt d'ions alcalins, comprenant les étapes suivantes : (i) la préparation d'un mélange contenant de l'eau, une zéolithe à teneur élevée en silice utilisée comme source principale de silice et d'alumine, un cation ammonium cyclique substitué par un alkyle utilisé comme agent d'orientation de structure organique (OSDA), une source de fer, et une source d'un ion de métal alcalin [Alk], afin d'obtenir un mélange de synthèse final ayant la composition molaire suivante : SiO2 : a Al2O3 : b Fe : c OSDA : d Alk : e H2O dans laquelle a est situé dans la plage allant de 0,001 à 0,2; b est situé dans la plage allant de 0,001 à 0,2; c est situé dans la plage allant de 0,01 à 2; d est situé dans la plage allant de 0,001 à 2; e est situé dans la plage allant de 1 à 200; (ii) la cristallisation du mélange obtenu en (i); (iii) la récupération de la substance cristalline obtenue en (ii); (iv) la calcination de la substance cristalline de l'étape (iii); et (v) l'élimination du cation de métal alcalin, présent dans la substance cristalline calcinée après l'étape (iv) afin d'obtenir une composition molaire finale : SiO2 : o Al2O3 : p Fe : q Alk dans laquelle o est situé dans la plage allant de 0,001 à 0,2, p est situé dans la plage allant de 0,001 à 0,2 et q est inférieur à 0,02.
