The present invention refers to a crystalline material that does not contain fluorides, with a composition in a roasted state corresponding to that of the material called ITQ-17 and that has a composition on an anhydrous base and in terms of oxide moles upon being synthesized, unroasted, represented by:XO:(1&#x2212;)YOGeOROwherein: It also refers to a process for synthesizing said material, as well as to the material obtained by said process and subjected to a step of post-synthesis to eliminate the organic component from its structure.

Synthesis of ITQ-17 in the absence of fluoride ions

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&#x3b8; angles of 6.9&#xb0;, 7.4&#xb0;, and 9.6&#xb0;, simultaneously. ITQ-16 zeolite in its calcinated form has the following empiric formula:(MXO):TOGeO:(1&#x2212;)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.
