Abstract (en)
[origin: CA3200348A1] The present invention relates to a method for producing a recycled catalyst comprising at least one group VIB metal M1 and/or at least one group VIII metal M2, optionally phosphorus and/or sulphur, and a carrier based on oxide(s). The method comprises recycling at least a portion of the at least one metal from a source catalyst comprising the metal M1 and/or the metal M2 in common with the recycled catalyst to be produced and involves: -extracting, by means of an extraction solution, the metal M1 and/or the metal M2 from said source catalyst, so as to obtain a solution of extracted metal/metals, then -impregnating the carrier with an impregnation solution derived from said a solution of extracted metal/metals, so as to obtain an impregnated substrate, said extracted metal or metals remaining in liquid phase from extraction to impregnation.
