A Systematic Visual Approach to Ionic Liquid Design for Carbon Dioxide Capture

摘要

Ionic liquids (ILs) have been introduced as potential replacement of conventional CO2 capturing solvents, for their negligible vapour pressure and high thermal stability. Besides, through matching cations and anions, ILs provide a flexibility to tune their properties. However, due to vast number of potential ILs, time and expense required determine suitable ILs for CO2 capture is unaffordable. In this work, a systematic visual approach to design IL as CO2 solvent, via property clustering technique and group contribution method has been developed. This approach allows visualisation of high-dimensional problem into two or three dimensions. A case study has been presented to elaborate application of the developed approach.
