Abstract

Un procedimiento para la preparación de zeolita L cristalina, comprendiendo dicho procedimiento: (A) la preparación de una mezcla de reacción auto-soportante que comprende al menos una fuente activa de silicio, al menos una fuente activa de alúmina y una fuente de hidróxido en cantidades suficientes para producir zeolita L, y suficiente agua para producir zeolita L, en el que la mezcla de reacción tiene una relación molar de OH-/ SiO2 de desde 0, 20 hasta 0, 40; y (B) el calentamiento de dicha mezcla de reacción a una temperatura desde aproximadamente 90°C hasta aproximadamente 200°C bajo condiciones de cristalización y en ausencia de una fase líquida externa agregada durante un tiempo suficiente para formar cristales de zeolita L.
