Abstract

This invention refers to a microporous crystalline material of zeolitic nature that has, in its calcined state and in the absence of defects in its crystalline matrix manifested by the presence of silanols, the empirical formula

x (M 1/n XO 2 ): y YO 2 :g GeO 2 :(1- g )SiO2
in which M is selected between H + , at least one inorganic cation of charge +n, and a mixture of both, X is at least one chemical element of oxidation state +3, Y is at least one chemical element with oxidation state +4 different from Si, x takes a value between 0 and 0.2, both included, y takes a value between 0 and 0.1, both included, g takes a value between 0 and 0.5, both included that has been denoted ITQ-55, a method for its preparation and its use.

First claim

What is claimed is:

in which
M is selected between H + , at least one inorganic cation of charge +n, and a mixture of both,
X is at least one chemical element of oxidation state +3,
Y is at least one chemical element with oxidation state +4 different from Si,
x takes a value between 0 and 0.2, both included,
y takes a value between 0 and 0.1, both included,
g takes a value between 0 and 0.5, both included,
and wherein the material, as synthesized, has an X-ray diffraction pattern with, at least, the angle values 2θ (degrees) and relative intensities (I/I 0 ):
