Abstract: The sulfides in catalytic cracking gasoline of No.2 oil refinery of Funshun were oxidized effectively with hydrogen peroxide in the presence of formic acid was investigated. The volumic fraction of oxidant, volumic ratio of formic acid and hydrogen peroxide, reaction temperature and reaction time was investigated. The optimal reaction conditions are that volumic fraction of oxidant is 6%，volumic ratio of formic acid and hydrogen peroxide is 3.5∶1，reaction temperature is 45 ℃ and reaction time is 60 min. Under the optimal tconditions, desulfurization rate of catalytic cracking gasoline is 76.4%.
