Abstract (en)
[origin: WO2019224088A1] The invention relates to a method for preparing an AFX-structure zeolite, said method comprising at least the following steps: i) in an aqueous medium, mixing an FAU-structure zeolite having a molar ratio SiO2 (FAU)/Al2O3 (FAU) of between 6.00 and 200 inclusive, an organic nitrogen-containing compound R, at least one source of at least one alkali and/or alkaline-earth metal M, the reaction mixture having the following molar composition: (SiO2 (FAU))/(Al2O3 (FAU)) of between 6.00 and 200, H2O/(SiO2 (FAU)) of between 1.00 and 100, R/(SiO2 (FAU)) of between 0.01 and 0.60, M2/nO/(SiO2 (FAU)) of between 0.005 and 0.45, limits included, until a homogeneous precursor gel is obtained; and ii) subjecting the precursor gel resulting from step (i) to hydrothermal treatment at a temperature of between 120°C and 220° C for a period of between 12 hours and 15 days.
