Patent ID: 8007765

Claim:
A porous crystalline material comprising a chemical composition in calcined state represented by the formula: x X 2 O 3 :n YO 2 :m GeO 2 wherein: (n+m) is at least 5; X is one or more trivalent elements; Y is one or more tetravalent elements other than Ge; x is an integer; and the Y/Ge ratio is greater than 0.1; and wherein the crystalline material has an X-ray diffraction pattern having the following main lines for its calcined state: (d ± 0.2) (Å) Relative intensity 18.852 vs 15.393 w 11.923 vw 8.887 vw 8.431 vw 8.039 vw 7.696 vw 3.770 vw 3.733 vw 3.662 vw 3.628 vw 3.471 vw 3.333 vw wherein “vs” signifies relative intensity 80-100, “w” signifies relative intensity 20-40, and “vw” signifies relative intensity 0-20, each calculated as a percentage with respect to the most intense peak.
