Abstract

A series of zeolites ZSM-5 has been synthesized in hydrothermal conditions at160°C by varying the time of HT treatment with the following molar compositionsof the precursor gel: 1.0 SiO2 : 0.01Al2O3 : 0.2 ТPAОН : 0.05Na2O : 50 H2O : 4.0 EtOH.Materials have been characterized by X-ray diffraction, transmission electronmicroscopy and nitrogen adsorption measurements. We have succeeded to synthesizeZSM-5 crystals with metastable aggregate-like morphology reproducibly and tofollow their evolution during HT treatment.
