This invention refers to a new zeolitic material included under the ITQ-16 denomination,
to the method for obtaining them and their use as catalysts.
This material, ITQ-16 zeolite, is characterized by having different ratios of
the different polymorphs A, B and C described as possible intergrowths in Beta
zeolite and which, therefore, show different X-ray diffraction patterns to that
described for Beta zeolite, showing the X-ray diffraction pattern for ITQ-16, as
it is synthesised, diffraction peaks at 2 angles of 6.9, 7.4,
and 9.6, simultaneously.
ITQ-16 zeolite in its calcinated form has the following empiric formula:
where T is one or various elements with +4 oxidation status, different of Ge
and Si; X is one or various elements with +3 oxidation status and M can be H+
or one or various inorganic cations with charge +n, t is comprised between 0 and
0.1, g is comprised between 0.001 and 0.33 and x is comprised between 0 and 0.2.
