Abstract
Un proceso mejorado para la separación de parafinas normales de una corriente de carga que comprende una mezcla de parafinas normales o isoparafinas, el cual proceso emplea un material adsorbente formado por una zeolita selectiva de formas, y comprende los pasos de: (a) mantener un flujo de fluido neto a través de una columna de material adsorbente, en una única dirección, la cual columna contiene por lo menos tres zonas en las que se producen funciones operativas separadas y que están interconectadas en serio, estando las zonas terminales de dicha columna conectadas de modo de posibilitar una conexión continua de dichas zonas, (b) mantener, en dicha columna, una zona de adsorción definida por el material adsorbente que se extiende entre una corriente de entrada de carga, en el límite de corriente arriba de dicha zona, y una corriente de salida de refinado, en el límite de corriente abajo de la misma.
