Title: DIRECT SYNTHESIS OF A SAPO MATERIAL WITH AFX STRUCTURE COMPRISING COPPER AND USE OF THIS MATERIAL
Abstract:
The invention concerns a method for preparing a SAPO material with AFX structure comprising copper, said method comprising at least the steps of mixing, in an aqueous medium, at least one source of aluminium, at least one source of silicon, at least one source of copper, at least one source of phosphorus, a complexing agent, TETA, and a structuring agent, TMHD, in order to obtain a gel, and hydrothermal treatment of said gel with a shear rate less than 50 s-1 in order to achieve crystallisation of said SAPO material with AFX structure comprising copper.
