Abstract (en)
[origin: WO2020212356A1] The present invention relates to a method for fast synthesis of an AFX-structure zeolite, which comprises at least: i) mixing, in an aqueous medium, an FAU-structure zeolite having a molar ratio SiO2 (FAU)/Al2O3 (FAU) of between 2.00 and 100, an organic nitrogen compound R, at least one source of at least one alkali and/or alkaline-earth metal M of valency n, with the following molar composition: (SiO2 (FAU))/(Al2O3 (FAU)) between 2.00 and 100, H2O/(SiO2 (FAU)) between 1 and 100, R/(SiO2 (FAU)) between 0.01 and 0.6, M2/nO/(SiO2 (FAU)) between 0.005 and 0.45, in which SiO2 (FAU) designates the amount of SiO2 supplied by the FAU zeolite, and Al2O3 (FAU) designates the amount of Al2O3 supplied by the FAU zeolite, until obtaining a homogeneous precursor gel; ii) hydrothermally treating said precursor gel obtained at the end of step i) under autogenous pressure at a temperature of between 120°C and 250°C, for 4 to 12 hours.
