Claim:
A zeolite microporous crystalline material having an empirical formula: x ( M 1/n XO 2 ): y YO 2 :SiO 2 wherein M is selected from H + , at least one inorganic cation of charge +n, or a mixture of both, X is at least one chemical element having an oxidation state of +3, Y is at least one second chemical element other than Si having an oxidation state +4, x has a value between 0 and 0.3, y has a value between 0 and 0.1, and wherein the material has an X-ray diffraction pattern comprising at least the following diffraction peaks at values of angle 2θ (degrees) and relative intensities as defined in Table 2: 2θ (degrees) ± 0.5 Intensity (I/I 0 ) 7.8 mf 8.6 d (h) 14.8 d 15.8 d 19.4 d 21.4 m 22.1 f 23.0 mf 26.3 m 27.6 d 32.0 d 43.9 d wherein d has a weak intensity between 0 and 20%, m has a medium intensity between 20 and 40%, f has a strong intensity between 40 and 60%, mf has a very strong intensity between 60 and 100%, and h is a peak of diffraction appearing as a shoulder.
