Abstract
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 2θ angles of 6.9°, 7.4°, and 9.6°, simultaneously. ITQ-16 zeolite in its calcinated form has the following empiric formula:(MXO):TOGeO:(1−)SiOwhere 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 Hor 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.
