Patent ID: 7947252

Claim:
A porous crystalline material, characterized in that it has a chemical composition in the calcined form represented by the formula: X 2 O 3 :n YO 2 :m GeO 2 in which (n +m) is at least 5, X is a trivalent element, Y represents one or more tetravalent elements other than Ge, and the ratio Y/Ge is greater than 1, and has a X-ray diffraction pattern whose principal lines for its uncalcined synthesized form are (d ± 0.2) Relative (Å) intensity 16.59 vs 11.63 vw 9.57 vw 8.31 vw 6.76 vw 4.81 vw 4.62 vw 4.27 w 3.64 w 3.15 w in which “vs” denotes relative intensity 80-100, “w” denotes relative intensity 20-40and “vw” denotes relative intensity 0-20, calculated as a percentage relative to the peak with greatest intensity.
