Abstract：The metal-organic framework material Fe/Cu-BTC was prepared by modification of Cu-BTC with FeCl2. The obtained materials were characterized by X ray diffraction (XRD), scanning electron microscope (SEM), X ray energy dispersive spectroscopy (EDS), inductively coupled plasma (ICP), N2 adsorption and X ray photoelectron spectroscopy (XPS). The static adsorption property, removal ratio of sulfide, dynamic adsorption and regeneration property of Fe/Cu-BTC were investigated. The results showed that the reduction of Cu(II) to Cu(I) happened in the Cu-BTC during the modification process of FeCl2 and the corresponding crystallinity decreased after modification with FeCl2 because of over reduction. Besides, with the increase of Fe/Cu molar ratio, the adsorption capacity of the adsorbents Fe/Cu-BTC for 1-propanethiol and ethyl sulfide increased first and then decreased. The sulfur capacity of Fe/Cu-BTC-0.15 with 0.15 molar ratio of Fe to Cu reached the highest level. It’s adsorption capacities for 1-propanethiol and ethyl sulfide were 32.3% and 46.3% higher than those of Cu-BTC respectively, the dynamic adsorption capacities of Fe/Cu-BTC-0.15 for 1-propanethiol and ethyl sulfide were 58.0% and 65.9% higher than those of Cu-BTC. The ratio of adsorption for 1-propanethiol and ethyl sulfide by Fe/Cu-BTC-0.15 were high up to 90.5% and 88.5% in the simulated oil with high sulfur content. The adsorption capacity of the regenerated Fe/Cu-BTC-0.15 for ethyl sulfide reached 91.3% of the fresh one.
