Patent ID: 7008612

Claim:
A porous crystalline material that, in a calcined state has a composition X 2 O 3 :nYO 2 :mZO 2 wherein X is a trivalent element, Z is Ge, Y is at least one tetravalent element other than Ge, (n+m) is at least 5, and the Y/Z ratio is at least 1, and the material, in its calcined form, has an X-ray diffraction pattern substantially coinciding with Relative 2θ(°) (a) intensity 6.4 VS 11.2 M 18.4 W 19.6 W 21.6 M 26.3 M 29.3 W (a) ±0.2 (a) ±0.2 wherein VS is a very strong relative intensity corresponding to a percentage of 80–100 with respect to the most intense peak; M is a medium relative intensity, corresponding to a percentage of 40–60 with respect to the most intense peak, and W is a weak relative intensity, corresponding to a percentage of 20–40 of the most intense peak.
