Abstract

Los procesos descritos incluyen hacer reaccionar un catalizador puro o agotado, o sorbente, con una solución que contiene un agente de extracción (tal como un ácido o base) De preferencia, el catalizador contiene tanto alúmina como un tamiz molecular (o un sorbente), y la reacción se realiza bajo condiciones relativamente moderadas. Así, el catalizador se puede reutilizar y en ciertos casos aún se mejora el desempeño del catalizador. Adicionalmente, los metales contenidos en el catalizador, tales como Na, Mg, A1, P, S, 01, K, Ca, y, Fe, Ni, Cu, Zn, Sr, Zn Sb, Ba, Pb, o sus óxidos equivalentes, se pueden remover del catalizador. Algunos de los metales que se remueven son relativamente valiosos (tales como los elementos de tierras raras de La, Ce, Pr y Nd).
