By using isopropanol as the phase transfer agent, three reaction systems that can realize the in-situ oxidative desulfurization of fuel oil are constructed.Through changing solvent ratio in the system, isopropanol-acetonitrile reaction system with a solvent ratio of 1:1 is determined as the best reaction system.Under the optimal reaction system, the single factor method is utilized to investigate the influences of the consumption of Pt/C, the type of acid-base additives, the initial sulfur content of the simulated fuel oil, and the type of organic sulfur compound on the desulfurization.The dynamics of the newly constructed desulfurization reaction system is studied.It is shown that the desulfurization efficiencies of simulated fuel oil by three reaction systems is in the order of high to low:isopropanol-acetonitrile, isopropanol-DMF, and isopropanol-deionized water, and the best solvent ratio is 1:1; The desulfurization effect of simulated fuel oil reaches the best under the action of 0.15 g Pt/C catalyst; KOH shows the best desulfurization effect among four kinds of acid-base additives; Initial sulfur content has a slight influence on the desulfurization effect; Under the same reaction conditions, the removal effects of different sulfides are in the order of high to low:DBT>4, 6-DMDBT>BT.
