摘 要:In order to further reduce the sulfur content in liquid hydrocarbon fuels,a desulfurization process by adsorption for removing alkyl dibenzothiophenes was *** of model gasoline by bentonite adsorbents loaded with silver nitrate was *** test results indicated that the bentonite adsorbents loaded with Ag + ions were effective for adsorbing the alkyl *** crystal structure of bentonite adsorbents was characterized by X-ray diffraction (XRD) and their acidity was measured by Fourier transform infrared (FT-IR) *** factors influencing the desulfurization capability,including the Ag + loading,the baking temperature,as well as the reaction temperature,were *** desulfurization efficiency was enhanced by increasing the Ag + loading and the best result was obtained at a silver loading of 7 m%.It was found that the adsorption capacity of the alkyl dibenzothiophenes on bentonite loaded with Ag + ions increased with a decreasing *** of the adsorbent could also improve the desulfurization capacity,and the optimum baking temperature was 423 K.
