The present invention provides a desulfurizing agent manufacturing method which is characterized in that a mixed aqueous solution containing a copper compound and a zinc compound and an aqueous solution of an alkali substance are mixed so that a precipitate is produced, the precipitate thus obtained is calcined, and a formed body of a copper oxide - zinc oxide mixture is obtained using a slurry of the calcined product obtained as described above, after which this formed body is impregnated with the elements iron or nickel and further calcined, and the calcined oxide body thus obtained is reduced with hydrogen. The present invention also provides a method for desulfurizing hydrocarbons using the desulfurizing agent thus obtained.
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.
