The EUO structure zeolite, comprising zeolites EU1, TPZ-3 and ZSM-50, is synthesized in the presence of seeds of another zeolite of a different structural type and/or different chemical composition of the crystal lattice. The synthesis is also carried out in the presence of a structuring agent. The EUO zeolite comprises an element X (Si or Ge) and an element T, chosen from Fe, Al, Ga, B, Ti, V, Zr, Mo, As, Sb, Cr and Mn. In the synthesis, seeds of a zeolite material comprising an element X<1> (Si or Ge) and T<1> (Fe, Al, Ga, B, Ti, V, Zr, Mo, As, Sb, Cr or Mn) are used, such that X<1> / T<1> is less than 200, this zeolite differing from the EUO zeolite to be prepared. Independent claims are also included for the EUO zeolites prepared by the process and their uses, and preparation of catalysts containing the zeolites and their uses. |
