摘要
The desulfurization of model gasoline by 5A molecular sieves loaded with Cu2+ was studied.Several factors which influence the desulfurization capability,including temperature,Cu2+ loading,baking temperature,as well as the ethanethiol concentration were investigated.In the range of adsorption temperature of 20℃45℃,it was found that the sorption capacity of ethanethiol on 5A molecular sieves loaded with Cu2+ increases with the temperature increasing.The desulfurization is enhanced by increasing the Cu2+ loading and the best result is obtained at the Cu2+ loading of 0.16mol/L.Baking of the sorbent can also improve the desulfurization capability,and the optimum baking temperature is 300℃.Two methods of the sorbent regeneration were compared in the experiment,the regeneration by baking is better than that by alcohol washing.
The desulfurization of model gasoline by 5A molecular sieves loaded with Cu^2＋ was studied. Several factors which influence the desulfurization capability, including temperature, Cu^2＋ loading, baking temperature, as well as the ethanethiol concentration were investigated. In the range of adsorption temperature of 20 ℃ - 45 ℃ , it was found that the sorption capacity of ethanethiol on 5A molecular sieves loaded with CuE＋ increases with the temperature increasing. The desulfurization is enhanced by increasing the Cu^2＋ loading and the best result is obtained at the Cu^2＋ loading of 0.16 mol/L. Baking of the sorbent can also improve the desulfurization capability, and the optimum baking temperature is 300 ℃ . Two methods of the sorbent regeneration were comoared in the exoeriment,the regeneration by baking is better than that by alcohol washing.
