Embodiment 1
[0042] Example 1: Add 18.2 mg of phosphotungstic acid to 10 mL of absolute ethanol and disperse with magnetic stirring at room temperature for 0.5 hours, then add 181.8 mg of hexagonal boron nitride and continue stirring for 0.5 hours, then transfer the mixture to a high-pressure reactor After hydrothermal reaction at 120°C for 4 hours, it was naturally cooled to room temperature, and then heat-treated in an oven at 100°C for 10 hours to obtain the high-efficiency catalyst.
[0043] Add 5mL BT model oil in double-necked jacket bottle, add the catalyst and 30wt%H of 0.02g embodiment 1 gained in oil product 2 o 2 , the molar ratio of sulfide to hydrogen peroxide in the fuel is 1:2 (the ratio of oxygen to sulfur is 2), and the reaction is performed under magnetic stirring in a constant temperature water bath at 20°C, while tap water is condensed and refluxed. During the reaction, the catalyst remains insoluble in the oil; the reaction During the process, 1 µL of the clear suspen...
Embodiment 2
[0044] Example 2: Add 29.8 mg of phosphotungstic acid to 10 mL of absolute ethanol and disperse with magnetic stirring at room temperature for 1.0 hour, then add 170.2 mg of hexagonal boron nitride and continue stirring for 1.0 hour, then transfer the mixture to a high-pressure reactor After hydrothermal reaction at 140°C for 6 hours, it was naturally cooled to room temperature, and then heat-treated in an oven at 110°C for 12 hours to obtain the high-efficiency catalyst.
[0045] Add 5mL of 4,6-DMDBT model oil into the double-necked bottle, add 0.04g of the catalyst obtained in Example 2 and H to the oil 2 o 2 , the molar ratio of sulfide to hydrogen peroxide in the fuel is 1:3, magnetically stirred and reacted in a constant temperature water bath at 30°C, and tap water is used to condense and reflux at the same time. During the reaction, the catalyst remains insoluble in the oil; during the reaction, take 1 µL of the clarified suspension was injected into GC-FID to detect t...
