Abstract

UN METODO DE DESACTIVACION ACTIVA DE RESIDUOS CATALIZADORES CORROSIVOS EN UN POLIMERO DE OLEFINA, Y NEUTRALIZACION SIMULTANEA DE ESOS RESIDUOS CORROSIVOS. EL POLIMERO QUE CONTIENE EL RESIDUO CATALITICO SE PONE EN CONTACTO CON UNA CANTIDAD EFECTIVA DE UN ALCALI O UNA SAL DE UN METAL ALCALINOTERREO DE ACIDO PERBORICO.
