<p>A new zeolite material designated EU-7 has a molar composition expressed by the formula: 0.5 to 2.5 R<Sub>2</Sub>0 : Y<Sub>2</Sub>0<Sub>3 </Sub>: at least 20 XO<Sub>2</Sub> : 0 to 600 H<Sub>2</Sub>0 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 aluminium, iron, chromium, vanadium, molybdenum, arsenic, antimony, manganese, gallium or boron and H<Sub>2</Sub>0 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 XO<Sub>2</Sub> (preferably silica), Y<Sub>2</Sub>0<Sub>3</Sub> (preferably alumina) and optionally an organic compound, most preferably butane-1, 4-diamine.</p> |
