离子液体强化的低温加氢脱硫脱氮耦合新过程

Deep desulfurization and denitrification of fuels has drawn extensive attention due to the poor quality of the oil and increasingly stringent regulations for environment. In this study, originally innovative designing and synthesising ionic liquids supported on aluminosilicates will be prepaed and used for low-temperature desulfurization and denitrification of gasoline and diesel fuel. the relationship will be illustrated between the properties of ionic liquids such as function groups, acid-base characters and catalytic activities such as solubility of hydrogen, film of ionic liquids. Furthermore, the ionic liquids will be grafted on the surface of supporter due to chemically bond. And then the bonding mechanism, the property and stability of the bond between ionic liquids and supporter will be studied. Experiments and molecular simulation will be used to study the mechanism of low-temperature deep desulfurization and denitrification with ionic liquid. Finally, optimized process parameters, kinetic model and rate-limited step will be obtained. Meanwhile, the reaction network of desulfurization and denitrification will be built up. Finally, the reaction network of the desulfurization and denitrification will be proposed, the whole process will be simulated and optimized.
