Title (EN) PROCESS FOR METALS RECOVERY FROM SPENT CATALYST
(FR) PROCEDE DE RECUPERATION DE METAUX DE CATALYSEUR EPUISE
Abstract: front page image
(EN)The process of this invention is directed to the removal of metals from an unsupported spent catalyst. The catalyst is subjected to leaching reactions. Vanadium is removed as a precipitate, while a solution comprising molybdenum and nickel is subjected to further extraction steps for the removal of these metals. Molybdenum may alternately be removed through precipitation.
(FR)L'invention concerne un procédé servant à la récupération de métaux d'un catalyseur épuisé non supporté. Le catalyseur est soumis à des réactions de lixiviation. Du vanadium est extrait en tant que précipité, alors qu'une solution contenant du molybdène et du nickel est soumise à des étapes d'extraction ultérieures en vue de la récupération de ces métaux. Le molybdène peut en outre être extrait par précipitation.
