The invention concerns a process for preparing an EU-1 zeolite having a XO 2 /Y 2 O 3 ratio in the range 10 to 100, comprising the following steps:n a) mixing, in an aqueous medium, at least one source of at least one oxide XO 2 , X being selected from silicon and/or germanium, at least one source of at least one oxide Y 2 O 3 , Y being selected from aluminium, iron, gallium and boron, and at least one organic template Q; b) drying the reaction mixture derived from step a) at a temperature of less than 200° C.; c) hydrothermal treatment of the dried reaction mixture derived from step b) in an autoclave, said dried reaction mixture not being in contact with a liquid phase at the bottom of the autoclave. |
