[0020] Example 1
[0021] Catalytic distillation desulfurization tower reactor with a diameter of 30 mm, a height of 500 mm, and a number of plates of 25, equipped with Raschig ring ceramic packing, filled with a height of 100 mm, 25% hydrogen peroxide, methyl tert-butyl The base ether is fed from the bottom of the tower through a metering pump in the gas phase at a rate of 80g / h, and the formic acid is fed from the top of the tower through a metering pump through a metering pump in countercurrent contact with methyl tert-butyl ether and oxidized by hydrogen peroxide. Function: Oxidize organic sulfide in methyl tertiary butyl ether to water-soluble sulfate. The bottom temperature of the tower is 90℃, the temperature of the oxidation reaction section is 80℃, the top temperature is 60℃, and the top reflux ratio is 1; after oxidation Water-soluble sulfates are formed and dissolved in the water reduced with hydrogen peroxide, and left at the bottom of the tower; the methyl tert-but
