Abstract

SE PRESENTA UN PROCESO QUE COMPRENDE LOS PASOS DE CONTACTAR UN RESIDUO DE CATALIZADOR DE HIDROGENACION DE METAL DEL GRUPO VIII QUE CONTENGA UNA SOLUCION DE POLIMEROS CON UNA RESINA QUELANTE, Y ESTA RESINA HA DE TENER IONES DE IMINODIACETATO, Y LA RECUPERACION DE UNA SOLUCION DE POLIMEROS CON MENOS DE 5 PPM POR PESO, BASADO EN LA SOLUCION, DEL METAL DE RESIDUO DE CATALIZADOR DE HIDROGENACION. EN UNA INCORPORACION PREFERIBLE, LA RESINA SE CONTACTA CON EL RESIDUO CATALIZADOR DE HIDROGENACION QUE CONTENGA UNA SOLUCION DE POLIMEROS MEZCLANDO PARTICULAS DE LA RESINA CON EL RESIDUO CATALIZADOR DE HIDROGENACION QUE CONTENGA UNA SOLUCION DE POLIMEROS BAJO AGITACION, Y LA SOLUCION DE POLIMEROS QUE CONTENGA MENOS DE 5 PPM DE METALES CATALIZADORES DE HIDROGENACION SE RECUPERA A LA RESINA Y LOS RESIDUOS CATALIZADORES DE HIDROGENACION PRECIPITADA RESULTANTES POR FILTRACION.
