Title (EN) METHOD FOR SEPARATING AND RECOVERING PRECIOUS METAL FROM REMANUFACTURING SOLUTION OF VANADIUM-CONTAINING DESULFURIZING CATALYST
(FR) PROCÉDÉ POUR SÉPARER ET RÉCUPÉRER DU MÉTAL PRÉCIEUX À PARTIR D'UNE SOLUTION DE RETRAITEMENT D'UN CATALYSEUR DE DÉSULFURATION CONTENANT DU VANADIUM
(KO) 바나듐 함유 탈황폐촉매의 재제조용액으로부터 유가금속의 분리 및 회수방법
Abstract: front page image
(EN) The present invention relates to a method for separating and recovering precious metals from a remanufacturing solution of a vanadium-containing desulfurizing catalyst and, more specifically, to a method for separating and recovering precious metals from a remanufacturing solution of a vanadium-containing desulfurizing catalyst, comprising the steps of: preparing a remanufacturing solution of a hydro desulfurizing catalyst by collecting a hydro desulfurizing catalyst and then adding an organic acid to the same; obtaining an organic phase by adding, to the remanufacturing solution, an extracting agent and a diluent so as to extract molybdenum and then extracting vanadium from the extracted filtrate; and adding, to the organic phase, a stripping agent so as to strip and recover vanadium.
(FR) La présente invention concerne un procédé pour séparer et récupérer des métaux précieux à partir d'une solution de retraitement d'un catalyseur de désulfuration contenant du vanadium et, plus particulièrement, un procédé pour séparer et récupérer des métaux précieux à partir d'une solution de retraitement d'un catalyseur de désulfuration contenant du vanadium, comprenant les étapes consistant à : préparer une solution de retraitement de catalyseur d'hydrodésulfuration par la récupération d'un catalyseur d'hydrodésulfuration puis par l'addition d'un acide organique à celui-ci ; obtenir une phase organique par l'addition, à la solution de retraitement, d'un agent d'extraction et d'un diluant de manière à extraire le molybdène puis extraire le vanadium du filtrat extrait ; et ajouter, à la phase organique, un agent de réextraction de manière à réextraire et à récupérer le vanadium.
(KO) 본 발명은 바나듐 함유 탈황폐촉매의 재제조용액으로부터 유가금속의 분리 및 회수방법에 관한 것으로, 더욱 구체적으로 수첨 탈황 폐촉매(hydro desulfurizing catalyst)를 수집한 후 유기산을 첨가하여 상기 수첨 탈황 폐촉매의 재제조용액을 제조하는 단계; 상기 재제조용액에 추출제와 희석제를 첨가하여 몰리브덴을 추출한 후 추출여액으로부터 바나듐을 추출하여 유기상을 얻는 단계; 및 상기 유기상에 탈거제를 첨가하여 바나듐을 탈거시킨 후 회수하는 단계를 포함하는 바나듐 함유 탈황폐촉매의 재제조용액으로부터 유가금속의 분리 및 회수방법에 관한 것이다.
