Disclosed herein are a desulfurizing agent for removing organic sulfur compounds, a preparation method thereof, and a method for removing organic sulfur compounds using the same. The desulfurizing agent consists of a copper- zinc-aluminum complex free of alkaline metal, with a large surface area. When being contacted with organic sulfur compounds, such as t-butylmercaptan, tetrahydrothiophene, dimethylsulfide, etc., the desulfurizing agent exhibits excellent desulfurization ability and is not degraded especially at high temperatures as high as 150 .sim. 350 ~C.

La présente invention concerne un agent désulfurant destiné à l'élimination des composés de soufre organiques, un procédé de préparation de l'agent désulfurant et un procédé d'élimination des composés de soufre organiques à l'aide de l'agent désulfurant. L'agent désulfurant consiste en un complexe cuivre-zinc-aluminium de grande surface spécifique et exempt de métaux alcalins. Quand il est mis au contact de composés de soufre organiques, tels que le t-butylmercaptan, le tétrahydrothiophène, le sulfure de diméthyle, etc., l'agent désulfurant présente une excellente capacité de désulfuration et il n'est pas dégradé, même à des températures élevées pouvant atteindre 150 ~ 350 °C.
