摘要：
A type of visible light photocatalyst kaolin/Cu2O was prepared from kaolin, CuCO3 center dot Cu(OH)(2)center dot XH2O, NaOH and C6H12O6 by means of hydrothermal method and was characterized by XRD, SEM and UV-vis. The desulfurization process for model fuel was studied based on a combination of photochemical reaction and liquid-liquid extraction. The effects of the doping of kaolin, volume of air, reaction time, and dosage of photocatalyst kaolin/Cu2O on the desulfurization efficiency were also investigated. When the load kaolin ratio of 20%, reaction time is 2 h, the volume of O-2 is 150 mL.min(-1), the amount of kaolin/Cu2O is 2 g.L-1 and solvent/oil ratio of 0.5, the desulfurization rate of model compound reached over 97 %.
