A. Hydrotreatment: under a certain temperature and pressure, diesel contact with hydrogen, the sulfur is converted into hydrosulfuric acid, then removed by pickling method. This method can effectively reduce the sulfur content in diesel, However the plant investment is large and the energy consumption is high.B. Solvent extraction method: choose an organic solvent that can form a substance with a large solubility with sulfur compounds, such as diphenyl ether, kerosene, etc., mix diesel with the solvent, so that the sul...
