Adsorptive Performance of Sulfur Compounds on Metal Organic Framework Material MIL-101

MIL-101 was synthesized by hydrothermal method.The fixed bed was employed to carry out the dynamic adsorption experiments for dimethyl sulfide,ethyl mercaptan and hydrogen sulfide at ambient temperature.The sulfuretted samples were characterized by XRD and TG-MS techniques.The density functional theory was used to calculate the adsorption energies of three sulfides over the MIL-101. It was found that the adsorption capacity is m(S)/m(MOFs)=24.2 mg/g, m(S)/m(MOFs)=14.9 mg/g and m(S)/m(MOFs)=5.8 mg...
