Preparation of Kaolin/Cu₂O Photocatalyst and its Application in the Photocatalytic Oxidation-Extraction Desulfurization

Abstract:

A type of visible light photocatalyst kaolin/Cu₂O was prepared from kaolin, CuCO₃·Cu(OH)₂·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 O₂ 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 %.
