Abstract
The present invention relates to a process for preparing zeolite crystals continuously, comprising the continuous introduction of a composition capable of generating zeolite crystals into at least one crystallization reaction zone subjected to stirring means, giving said composition a flow characterized by a relative Reynolds number Rer of between 40 and 50 000, and the continuous recovery of the crystals formed according to a flow characterized by a net Reynolds number Ren of between 1 and 1500.
