Crystalline aluminosilicate PSH-3 and its process of preparation

摘要

The present invention relates to a new zeolite material having a composition (molar ratios of the oxides) corresponding to the formula: M2/nO.Al2O3.(20-150) SiO2 (M represents n-valent cation) to a process for the production thereof using hexamethylene imine and to the use of the zeolite material as a catalyst in the conversion of methanol and/or dimethyl ether to hydrocarbons.
