The invention relates to a method for treating and upgrading a hydrocarbon containing acidic species such as mercaptans, comprising: (a) contacting the hydrocarbon, in the essential absence of oxygen, with a first phase of a treatment composition containing water, dissolved alkali metal hydroxide, cobalt phthalocyanine sulfonate, and dissolved alkylphenylates and having at least two phases, (i) the first phase containing water, alkali metal alkylphenylate, dissolved alkali metal hydroxide, and dissolved sulfonated cobalt phthalocyanine, and (ii) the second phase containing water and dissolved alkali metal hydroxide; and then (b) separating an upgraded hydrocarbon.
La présente invention se rapporte à un procédé de traitement et de valorisation d'un hydrocarbure contenant des espèces acides du type mercaptans. Ce procédé consiste (a) à mettre en contact l'hydrocarbure, sensiblement en l'absence d'oxygène, avec une première phase d'une composition de traitement contenant de l'eau, un hydroxyde métallique alcalin dissout, un sulfonate de cobalt phtalocyanine et des alkylphénylates dissouts, et présentant au moins deux phases, (i) la première de ces phases contenant de l'eau, un alkylphénylate métallique alcalin, un hydroxyde métallique alcalin dissout et une phtalocyanine de cobalt sulfonée et dissoute, et (ii) la seconde de ces phases contenant de l'eau et un hydroxyde métallique alcalin dissout ; puis (b) à séparer un hydrocarbure valorisé.
