Microporous crystalline zeolite material (zeolite ITQ-22), synthesis method thereof and use of same as a catalyst

A new microporous, crystalline, zeolitic material (I), designated 'ITQ-22', contains silicon dioxide and optionally germanium oxide, hydrogen ions, inorganic cations, trivalent elements and/or other tetravalent elements, and is characterized by its empirical formula and X-ray diffraction pattern. A new microporous, crystalline, zeolitic material (I), designated 'ITQ-22', has formula (I) (in the calcined state and in the absence of crystal lattice defects shown by the presence of silanols) and an X-ray diffraction pattern, in 'as-synthesized' form, with maxima at 2 theta values of 8.02 degrees (very strong), 8.43 degrees (very strong), 9.31 degrees (medium), 10.64 degrees (very strong), 20.26 degrees (medium), 21.81 degrees (strong) and 22.53 degrees (very strong). x (M1/nXO2) : y YO2 : z GeO2 : (1-z) SiO2 (I) M = H+ or inorganic cation(s) of charge n+; X = element(s) in the +3 oxidation state, preferably Al, Ga, B, Fe or Cr; Y = element(s) in the +4 oxidation state (other than Si or Ge), preferably Ti, Sn or Cr; x = less than 0.2 (preferably less than 0.1; possibly zero); y = less than 0.1 (preferably less than 0.05; possibly zero); and z = less than 0.8 (preferably 0.005-0.5; possibly zero). (I) has an X-ray diffraction pattern, in calcined form, with maxima at 2 theta values of 6.97 degrees (medium), 8.00 degrees (very strong), 8.40 degrees (very strong), 9.28 degrees (medium), 10.62 degrees (very strong), 20.18 degrees (medium), 21.74 degrees (strong) and 22.54 degrees (very strong). An Independent claim is also included for the preparation of (I).
