Abstract

UN PROCEDIMIENTO PARA PREPARAR ZEOLITAS TIPO L. SE PREPARAN POR UNA TECNICA DE NUCLEACION EN LA QUE UNA PRIMERA MEZCLA ACUOSA DE AGUA, UNA FUENTE DE SILICE, UNA FUENTE DE ALUMINA, UN HIDROXIDO DE METAL ALCALINO, Y OPCIONALMENTE UNA FUENTE DE CATION DE MUESTRA ORGANICO SE PREPARA, SE HOMOGENEIZA Y SE ENVEJECE A UNA TEMPERATURA Y DURANTE UN TIEMPO SUFICIENTE DE MODO QUE SE INICIE Y SE ESTABLEZCA LA CRISTALIZACION. ESTA PRIMERA MEZCLA ACUOSA SE AÑADE A UNA SEGUNDA MEZCLA ACUOSA HOMOGENEIZADA RECIEN PREPARADA DE SUSTANCIALMENTE LA MISMA COMPOSICION QUE LA PRIMERA MEZCLA, LA CUAL SE MANTIENE A TEMPERATURAS ELEVADAS SUFICIENTES PARA ASEGURAR LA CRISTALIZACION DE LA FASE DE ZEOLITA DESEADA.
