Abstract
Abstract A new zeolite material designated EU-12 has a molar composition expressed by the formula: 0.5 to 2.0 R2O: Y2O3: at least 5 XO2: 0 to 1000 H2O wherein R is a monovalent cation or 1/n of a cation of valency n, X is silicon and/or germanium, Y is one or more of aluminum, iron, chromium, vanadium, molybdenum, arsenic, antimony, manganese, gallium or boron and H2O is water of hydration additional to water notionally present when R is H, and having an X-ray powder diffraction pattern substantially as set out in Table 1. The zeolite material is prepared from a reaction mixture containing XO2 (preferably silica), Y2O3 (preferably alumina) and an organic compound, most preferably a tetramethylammonium compound.
