Example Embodiment
[0014] A method for deep desulfurization of gasoline (reference figure 1 ), the method uses oxidative desulfurization technology. In the method of the present invention, the oxidant used is solid manganese dioxide and includes the following steps:
[0015] ①In the container of gasoline to be deeply desulfurized, add ionic liquid and solid manganese dioxide in sequence to form a three-phase system; among them, the ionic liquid is (imidazole ionic liquid)[BMIM]BF 4 , [BMIM]PF 6 , [BMIM]Cl, [EMIM]BF 4 , [EMIM]PF 6 Or [EMIM]Cl; In the gasoline to be deeply desulfurized, the mass fraction of sulfur is 0.05% as the conversion standard, and the mass ratio of ionic liquid to gasoline is 1:10-20, and the ratio of solid manganese dioxide to gasoline is Mass ratio 1:100~1000;
[0016] ②Place the above-mentioned container in a microwave environment with a frequency of 2.45GHZ and a power of 100-1000W, and stir at a temperature of 20-60℃ for at least 30 minutes to carry out a deep oxidative de...
