Abstract:
1. A microporous crystalline material of a zeolitic nature with a chemical composition in the calcinated and anhydrous state that can be represented by the empirical formula: wherein x has a value between 0 and 0.2; y has a value between 0 and 0.1; z has a value between 0 and 0.67; being at least one of z, x and y above zero: M is selected between H+ and inorganic cations with +n charge; X is at least a chemical element in a+3 oxidation state; Y is at least a chemical element in a+4 oxidation state; T is at least a chemical element in a+4 oxidation state, wherein the material, as synthesised, has an X-ray diffraction pattern of and wherein the material in a calcinated and anhydrous state has an X-ray diffraction pattern of: wherein vw means a very weak relative intensity, between 0 and 20%; w means a weak relative intensity, between 20 and 40%; m means an average relative intensity, between 40 and 60%; s means a strong relative intensity, between 60 and 80%; vs means a very strong relative intensity, between 80 and 100%.
