Abstract | A method for producing a desulfurizing agent characterized in that it comprises admixing a mixed aqueous solution containing a copper compound and a zinc compound with an alkaline aqueous solution to thereby form a precipitate, calcining the resultant precipitate, providing a molding of a copper oxide-zinc oxide mixture from the resultant calcined product, incorporating iron or nickel into the molding through impregnation, again calcining the product thus obtained and reducing the resultant calcined oxide with hydrogen, a method for desulfurizing a hydrocarbon stock using the desulfurizing agent.
L'invention concerne un procédé relatif à la fabrication d'un agent de désulfuration qui comprend les étapes suivantes: adjonction d'une solution aqueuse alcaline à une solution aqueuse mélangée à base de composé de cuivre et de composé de zinc pour former un précipité, calcination du précipité résultant, réalisation d'un moulage de mélange d'oxyde de cuivre et d'oxyde de zinc à partir du produit résultant calciné, adjonction de fer ou de nickel dans le moulage par imprégnation, nouvelle calcination du produit ainsi obtenu et réduction de l'oxyde calciné résultant avec de l'hydrogène. L'invention concerne en outre un procédé de désulfuration de charge d'hydrocarbure à l'aide de l'agent de désulfuration considéré. |
