Abstract
The invention concerns a process for preparing a copper-comprising SAPO material with AFX structure, comprising at least the steps of mixing, in an aqueous medium, at least one aluminum source, at least one silicon source, at least one copper source, at least one phosphorus source, a TETA complexing agent and a TMHD structuring agent, in order to obtain a gel, and hydrothermal treatment of said gel with a shear rate of less than 50 sin order to obtain crystallization of said copper-comprising SAPO material with AFX structure.
