Metal-organic framework compound Co-BTC was synthesized under hydrothermal conditions and characterized by XRD and IR. Effects of airspeed and moisture content on adsorptive separation of thiophene by Co-BTC were studied by fixed adsorption bed breakthrough curve, and the adsorbent was reactivated through solvent toluene washing. The results show that ,with the increase of airspeed, saturated adsorption capacity of Co-BTC reduces;sulfur saturated adsorption capacities of Co-BTC with water and without water are 1.50%and 2.05%(wt) respectively, desulfurization saturated adsorption capacity was reduced by 27%.To use molecular sieve stratification fill adsorption column technique can increase Co-BTC saturated adsorption capacity to 2.02 %, saturated adsorption capacity of regenerated adsorbent for thiophenic sulfur in model oil is 2.02%, regeneration rate reaches 99%.
