Abstract
SE DESCRIBE UN PROCEDIMIENTO DE PREPARACION DE ZEOLITAS 5A ESTABLES POR INTERCAMBIO CALCICO DE UNA ZEOLITA 4A CRISTALIZADA A PARTIR DE UN MEDIO DE SINTESIS DE DEBIL BASICIDAD, LA RELACION MOLAR NA2 O/H2 O DE DICHO MEDIO SIENDO INFERIOR A 1,3 10 ELEVADO -2. ESTAS ZEOLITAS CONSERVAN SU CAPACIDAD DE ADSORCION Y SU SELECTIVIDAD EN EL TRANSCURSO DE CICLOS DE ADSORCION LARGAMENTE REPETIDOS Y DE OPERACIONES DE REGENERACION OXIDANTE. SE UTILIZAN CON EXITO EN LA SEPARACION DE LAS PARAFINAS NORMALES Y DE LAS ISOPARAFINAS.
