Microporous crystalline zeolite material, zeolite itq-28, production method thereof and use of same

Abstract

The invention relates to a microporous crystalline zeolite material, zeolite ITQ-28, the production method thereof and the use of same. More specifically, the invention relates to a microporous crystalline zeolite material, ITQ-28, which, in the calcined state and in the absence of defects in the crystalline lattice thereof, manifested by the presence of silanols, is characterised by having empirical formula x (MXO): y YO: SiO, wherein: M is selected from H, at least one inorganic cation with charge +n, preferably alkalines or alkaline earths, and a mixture of both; X is at least one chemical element in oxidation state +3, preferably Al, Ga, B, Fe, Cr or mixtures thereof; Y is at least a chemical element in oxidation state +4, which is different from Si, preferably Ge, Ti, Sn, V or mixtures of same; x has a value of between 0 and 0.2 inclusive; and y has a value of between 0 and 0.1 inclusive. The invention is further characterised in that the material as it is synthesised has an x-ray diffraction pattern with at least values of angle 2θ (degrees) and the relative intensities given in table 1. The invention also relates to the method of preparing said material and to the use thereof in the conversion of organic compounds.
