Abstract

METODO DE PREPARACION DE ZEOLITAS L. COMPRENDE EL CALENTAMIENTO A UNA TEMPERATURA NO INFERIOR A 70JC DE UN PRIMER GEL DE CRISTALIZACION DE ZEOLITA L, CONSTITUIDO POR UNA MEZCLA ALCALINA DE AGUA, UNA FUENTE DE SILICIO Y UNA FUENTE DE ALUMINIO, EN CANTIDADES QUE PERMITAN OBTENER UNAS RELACIONES MOLARES, COMO OXIDOS, DE M2/N, O/SIO2, O,22-0,36; H2O/M2/NO, 25-90; Y SIO2/AL2O3, 5,7-15, DONDE M ES UN CATION DE VALENCIA N; SEPARACION DE LA ZEOLITA L FORMADA Y UTILIZACION DE AL MENOS UNA PARTE DE LAS AGUAS MADRES COMO COMPONENTE DE UN SEGUNDO GEL DE CRISTALIZACION DE ZEOLITA L, EN EL QUE SE SELECCIONA LA ALCALINIDAD PARA SUPRIMIR LA FORMACION DE ZEOLITA W. ESTAS CEOLITAS TIENEN APLICACIONES COMO BASE DE CATALIZADORES EN EL PROCESO DE AROMATIZACION DE HIDROCARBUROS ACICLICOS.
