类离子液体——深共融溶剂对燃油中有机硫化物萃取脱除过程研究

Organic sulfide in fuels has become an important reason for the formation of haze weather. The desulfurization of fuels has become a frontier scientific topic demanding prompt solution. Research shows that the emergency of ionic liquids analogues-deep eutectic solvents has provided a new opportunity for the deep extraction desulfurization of fuels because of their cheap and easily obtained raw materials, higher extraction desulfurization efficienies,simple and environmental friendly synthesis process. This project will design, synthesize and screen deep eutectic solvents for the desulfurization process. Through the study of the main factors that affect the desulfurization process, optimization of extraction parameter and extraction process will be realized. And the relationship between the structure and desulfurization ability of deep eutectic solvents will be constructed. At the same time, the suitable methods that can be used for the reuse of deep eutectic solvents will be investigated. Finally, experimental and theoretical calculation will be used to reveal the extraction mechanisms. With the above study, the theoretical foundation of desulfurization process for the directional design of deep eutectic solvents will be built, which will be beneficial for the smart design of deep eutectic solvents and the adjustment of desulfurization process. The above study will provide a new theoretical and technological support for deep desulfurization of fuels.
