Abstract[English]
The present invention relates to a process for producing a recycled catalyst comprising at least one group VIII metal M1 and comprising no group VIB metal and an oxide-based support, said process comprising at least one step of removing at least some of the carbon present on the source catalyst by washing and/or heat treatment at a temperature of less than 300°C, using an extraction solution to extract the metal M1 from said catalyst resulting from the step of removing at least some of the carbon, to give a solution of extracted metal(s), and at least one step of impregnating a support with at least one impregnation solution derived from said solution of extracted metal(s), to give an impregnated support, said extracted metal(s) remaining in the liquid phase from the extraction until impregnation.[French]
La présente invention concerne un procédé de production d'un catalyseur recyclé comprenant au moins un métal M1 du groupe VIII et ne comprenant pas de métal du groupe VIB et un support à base d'oxyde(s) dans lequel comprenant au moins une étape d'élimination d'au moins une partie du carbone présent sur le catalyseur source par lavage et/ou traitement thermique à une température inférieure à 300°C, une extraction par une solution d'extraction du métal M1 dudit catalyseur issu de l'étape d'élimination d'au moins une partie du carbone, pour obtenir une solution de métal/métaux extrait(s), et au moins une étape d'imprégnation d'un support par au moins une solution d'imprégnation issue de ladite solution de métal/métaux extrait(s), pour obtenir un support imprégné, ledit ou lesdits métaux extraits restant en phase liquide depuis l'extraction jusqu'à l'imprégnation.
