Photocatalytic oxidative desulfurization of gasoline in[BMIm]Cu_2Cl_3 ionic liquid was studied.A500-W high-pressure mercury lamp was used as the light source for irradiation,nano-TiO2 was used as thephotocatalyst and air was introduced by a gas pump to supply O_2 as the oxidant.Influence of the ratio ofV(ionic liquid) to V(oil) and the TiO_2 addition on the desulfurization rate of gasoline was investigated.Anoxidative kinetics equation was founded.The results showed that the [BMIm]Cu2CIs ionic liquid was aneffective extractant for the desulfurization of gasoline.The appropriate TiO_2 addition was 0.05 g in 50 mLof reaction mixture.The yield of desulfurized gasoline could reach 98.2% after being subjected to reactionfor 2 h under the conditions of adopting a ratio of V(ionic liquid):V(oil)=1:4,an air flow of 100 mL/min anda TiO_2 addition dosage of 0.05 g.The kinetics reaction for photo-oxidation of gasoline was a first-orderreaction with an apparent rate constant of 1.9664 h~(-1)and a half-time of 0.3525 h.

The yield of desulfurized gasoline could reach 98.2% after being subjected to reactionfor 2 h under the conditions of adopting a ratio of V (ionic liquid): V (oil) = 1: 4, an air flow of 100 mL / min anda TiO 2 addition dosage of 0.05 g. Kinetic reaction for photo-oxidation of gasoline was first-order reaction with an apparent rate constant of 1.9664 h ~ (- 1) and a half-time of 0.3525 h.
