Title (EN) RECOVERY OF PALLADIUM FROM CATALYST MATERIALS
(FR) RÉCUPÉRATION DE PALLADIUM À PARTIR DE MATÉRIAUX CATALYSEURS
Abstract: front page image
(EN)Disclosed is a process for recycling palladium-containing catalyst materials, wherein the process comprises: (a) grinding the palladium-containing catalyst in a milling module; (b) removing palladium from the palladium-containing catalyst using a removal composition; (c) optionally (i) separating the palladium-containing catalyst from the first removal composition using liquid-solid separation means subsequent to palladium removal to yield a solid and a liquid, and (ii) rinsing the solid with a first rinse subsequent to separation. The process can efficiently recover palladium from the catalyst materials while minimizing the amount of chemicals and other resources used.
(FR)L'invention concerne un procédé de recyclage de matériaux de catalyseur contenant du palladium, le procédé consistant à : (a) broyer le catalyseur contenant du palladium dans un module de broyage; (b) éliminer le palladium du catalyseur contenant du palladium à l'aide d'une composition d'élimination; (c) éventuellement (i) séparer le catalyseur contenant du palladium de la première composition d'élimination à l'aide d'un moyen de séparation liquide-solide après l'élimination du palladium pour obtenir un solide et un liquide, et (ii) rincer le solide avec un premier rinçage après la séparation. Le procédé permet de récupérer efficacement du palladium à partir des matériaux catalyseurs tout en réduisant au minimum la quantité de produits chimiques et d'autres ressources utilisées.
