Abstract

PROCEDIMIENTO PARA PREPARAR ZEOLITA L. CONSISTE EN CALENTAR UNA MEZCLA ALCALINA DE REACCION ENTRE 200 Y 250GC, DURANTE 24 HORAS, PARA FORMAR CRISTALITOS DE ZEOLITAS L DE FORMA CILINDRICA E INTERRUMPIR LA CRISTALIZACION ANTES DE LA TRANSFORMACION DE IMPORTANTES CANTIDADES DE ZEOLITA L EN OTRAS FASES CRISTALINAS. LA MEZCLA DE REACCION COMPRENDE AGUA, SILICE Y ALUMINA CON UNA COMPOSICION QUE TIENE LA PROPORCION MOLAR M2O/SI2, DE 0,22 A 0,30, H2O/M2O DE 25 A 45 Y SIO/AL2O3 DE 10 A 12. SIENDO M UN CATION ALCALINO. O
