PROCESS FOR PREPARING AN IZM-2 ZEOLITE IN THE PRESENCE OF A NITROGENOUS ORGANIC STRUCTURING AGENT IN HYDROXIDE FORM AND OF AN ALKALI METAL CHLORIDE, IN FLUORINATED OR NON-FLUORINATED MEDIUM
PROCESS FOR PREPARING AN IZM-2 ZEOLITE IN THE PRESENCE OF A NITROGENOUS ORGANIC STRUCTURING AGENT IN HYDROXIDE FORM AND OF AN ALKALI METAL CHLORIDE, IN FLUORINATED OR NON-FLUORINATED MEDIUM
The invention relates to a process for preparing an IZM-2 zeolite, comprising at least:i) mixing, in aqueous medium, of at least one source of at least one tetravalent element X (XO2), at least one source of at least one trivalent element (Y2O3), 1,6-bis(methylpiperidinium)hexane dihydroxide, at least one source of at least one alkali metal M of valency n chosen from alkali metal chlorides, n being an integer greater than or equal to 1, M being chosen from lithium, potassium, sodium and caesium, and the mixture of at least two of these metals, and optionally in the presence of a source of at least one fluoride anion, BF, the mixture having a specific molar composition to obtain a homogeneous precursor gel;ii) hydrothermal treatment of said precursor gel.展开▼
