Abstract:
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:   SiO 2 :a Al 2 O 3 :b Fe: c OSDA: d Alk: e H 2 O 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: SiO 2 :o Al 2 O 3 :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.
