摘要

Abstract

When evaluating ionic liquids (ILs) for extractive desulfurization (EDS) of fuel oils

the inevitable presence of water in the system may have a significant and in many cases strongly negative effect. However

few studies have considered this particular issue and a promoted water effect on EDS is scarcely reported. In this work

COSMO-RS was firstly employed to calculate the capacity and selectivity for EDS of various IL/H

O mixtures

which cover different IL characters and a wide water concentration range. Experiments were then conducted with a representative IL[C

MIM

]

whose stable and even promoted extraction performance with a small amount of water was suggested by COSMO-RS. Through analyses of the desulfurization ratio

the crosssolubility and the water content in the desulfurized fuel

the promoted effect of water within a certain range (10 wt%) was experimentally demonstrated. Moreover

such effect of water was explained combining the viscosity

the solvent-solute interactions and the COSMO-RS based analysis.
