NOVEL PROCESS FOR PREPARING ZEOLITE EU-1

摘要

The invention describes a process for preparing a zeolite EU-1 having an XO2/Y2O3 ratio between 10 and 100 that comprises the following steps: a) mixing, in an aqueous medium, of at least one source of at least one oxide XO2, X being chosen from silicon and/or germanium, of at least one source of at least one oxide Y2O3, Y being chosen from aluminium, iron, gallium and boron and of at least one organic structurant Q, b) drying the reaction medium derived from step a) at a temperature below 200°C, c) hydrothermal treatment of the dry reaction mixture derived from step b) in an autoclave, said dry reaction mixture not being in contact with a liquid phase at the bottom of the autoclave.
