Title (EN) PROCESS FOR PREPARING A SPENT CATALYST FOR PRECIOUS METALS RECOVERY
(FR) PROCÉDÉ DE PRÉPARATION D'UN CATALYSEUR USÉ POUR LA RÉCUPÉRATION DE MÉTAUX PRÉCIEUX
Abstract:
(EN) A process is provided for preparing a spent noble metal fixed-bed catalyst for precious metals recovery, comprising: a) adding the catalyst to a caustic solution to wash the spent catalyst and to make a wash slurry having an alkaline pH, wherein the spent catalyst has been in contact with chloroaluminate ionic liquid catalyst, and wherein the spent catalyst comprises from 5 to 35 wt% chloride; and b) filtering the wash slurry and collecting: i) a filter cake having from at least 70 wt% of the chloride in the spent catalyst removed and having the noble metals retained, and ii) a wash filtrate. Also provided is a filter cake comprising a washed consolidated cake having 40 to 75 wt% solids, a cake moisture content from 25 to less than 60 wt%, 0.1 to 1.5 wt% total noble metals, and a residual chloride content of from zero to less than 4 wt%.
(FR) L'invention concerne un procédé de préparation d'un catalyseur à lit fixe usé à base de métaux nobles pour la récupération de métaux précieux, comprenant les étapes consistant à : a) ajouter le catalyseur à une solution caustique afin de laver le catalyseur usé et de produire une boue de lavage présentant un pH alcalin, le catalyseur usé ayant été en contact avec un catalyseur de liquide ionique de type chloroaluminate et le catalyseur usé comprenant de 5 à 35 % en poids de chlorure ; et b) filtrer la boue de lavage et recueillir : i) un gâteau de filtration dont au moins 70 % en poids du chlorure dans le catalyseur usé sont éliminés et retenant les métaux nobles et ii) un filtrat de lavage. L'invention concerne également un gâteau de filtration comprenant un gâteau lavé consolidé comprenant de 40 à 75 % en poids de matières solides, une teneur en humidité de 25 à moins de 60 % en poids, de 0,1 à 1,5 % en poids de métaux nobles totaux et une teneur en chlorure résiduel de 0 à moins de 4 % en poids.
