New microporous, crystalline zeolite ITQ-22, useful as catalyst or catalyst component, e.g. for cracking, hydrocracking, isomerization, alkylation, acylation or oxidation reactions

摘要

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 2theta values of 8.02[deg] (very strong), 8.43[deg] (very strong), 9.31[deg] (medium), 10.64[deg] (very strong), 20.26[deg] (medium), 21.81[deg] (strong) and 22.53[deg] (very strong). x (M 1 / nXO 2) : y YO 2 : z GeO 2 : (1-z) SiO 2 (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 2theta values of 6.97[deg] (medium), 8.00[deg] (very strong), 8.40[deg] (very strong), 9.28[deg] (medium), 10.62[deg] (very strong), 20.18[deg] (medium), 21.74[deg] (strong) and 22.54[deg] (very strong). An independent claim is also included for the preparation of (I).
