Abstract

Síntesis de zeolita Beta. En la presente invención se reivindica un nuevo método de síntesis de zeolita Beta, caracterizado porque en la preparación de la mezcla de síntesis se evita la presencia de cationes alcalinos. La zeolita Beta obtenida se caracteriza por su pequeño tamaño de cristal, su capacidad de formar suspensiones coloidales estables y porque su calcinación permite obtener la forma ácida sin recurrir a procesos de intercambio catiónico. Se reivindica también el uso del material obtenido en procesos catalíticos de transformación de hidrocarburos, para preparación de membranas zeolíticas y como activador de otras síntesis de zeolitas. El método consiste en el calentamiento a 363-473K de una mezcla de reacción que contiene una fuente de silicio, una fuente de aluminio, un catión orgánico director de estructura como hidróxido y agua, evitándose la presencia de cationes alcalinos. Se obtiene una suspensión coloidal de zeolita Beta de la que puede separarse la zeolita.
