Title (EN) HYDROPROCESSING USING REJUVENATED SUPPORTED HYDROPROCESSING CATALYSTS
(FR) HYDROTRAITEMENT UTILISANT DES CATALYSEURS RENOUVELÉS SUPPORTÉS D'HYDROTRAITEMENT
Abstract: front page image
(EN)Methods for hydroprocessing of hydrocarbon feedstocks, including hydrodesulfurization and hydrodenitrogenation, using rejuvenated supported metallic catalysts are provided. The supported metallic catalysts comprised of a Group VIII metal, a Group VIB metal, are rejuvenated by a process making use of these metals, an organic complexing agent, and optionally an organic additive. The rejuvenation includes stripping and regeneration of a spent or partially spent catalyst, followed by impregnation with metals and at least one organic compound. The impregnated, regenerated catalysts are dried, calcined, and sulfided.
(FR)La présente invention concerne des procédés d'hydrotraitement de charges d'hydrocarbures, comprenant l'hydrodésulfurisation et l'hydrodénitrogénation, en utilisant des catalyseurs métalliques supportés renouvelés. Les catalyseurs métalliques supportés comprennent un métal du groupe VIII, un métal du groupe VIB, sont renouvelés par un procédé utilisant ces métaux, un agent complexant organique, et éventuellement un additif organique. Le renouvellement comprend les étapes consistant à démétalliser et à régénérer un catalyseur épuisé ou partiellement épuisé, suivies par l'imprégnation avec des métaux et au moins un composé organique. Les catalyseurs imprégnés, régénérés sont séchés, calcinés, et sulfurés.
