Abstract

La zeolita L, con morfologia cilindrica y excelentes propiedades como una base de catalizador, se puede preparar con elevada cristalinidada y contaminacion reducida, aun en sintesis a gran escala en que pueden ocurrir fluctuaciones en las composiciones de gel, empleando una composicion de gel que tiene las siguientes relaciones molares de los componentes: 2.64-2.67M2/nO:Al2O3:8.8-9.7 SiO2:145-160 H2O en que M es un cation de valencia n, especialmente el potasio. La relacion de M2/nOSiO2 es preferiblemente al menos de 0.275.
