Abstract
Un proceso para el tratamiento de un residuo con contenido de un catalizador de metal pesado, a partir de la produccion de un ácidopolicarboxílico aromático con solubilidad en agua de menos de 1% en peso a una temperatura de 25°C quecomp rende la disolucion , esencialmente, de todo elresiduo en un medio acuoso, precipitando los componentes metálicos del catalizador mediante la inclusion en el medio acuoso de aniones que formansales de metal y separando el precipitadodel med io acuoso.A process for the treatment of a residue containing a heavy metal catalyst, starting from the production of an aromatic polycarboxylic acid with a solubility in water of less than 1% by weight at a temperature of 25 ° C that makes up the solution, essentially , of all the residue in an aqueous medium, precipitating the metal components of the catalyst by including in the aqueous medium metal-forming anions and separating the precipitate from the aqueous medium.
