Abstract:
1. A porous crystalline material that, in a calcined state has a composition 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 (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.
