Faujasite type zeolites have found Widespread use in industrial applications, both as catalysts and as adsorbents. EMT (Elf Mulhouse Two), the hexagonal polymorph of faujasite, is prepared in 8 days at 110{degrees}C from a synthesis gel containing 18-crown-6 as organic template. In this work it was aimed at developing a reproducible method to prepare kilogram batches of highly crystalline and pure EMT, focusing in particular on the raw material quality, the template content and the influence of agitation (type and rate) on the ageing and crystallization periods. The characterization of the obtained materials is also reported (XRD, chemical and thermal analyses, SEM, NMR spectroscopy ... ).
