| Outline of Final Research Achievements |
On the dissolution mechanism in the ionic liquid - carbon dioxide system, various ionic liquids with different structures were synthesized and the effect of cation and anion on gas solubility was clarified. We clarified the dependence of temperature and composition on the transport phenomenon of ionic liquid. Thermophysical properties when carbon dioxide was dissolved in the ionic liquid differed from the dissolution enthalpy due to the structure and pressure of the ionic liquid, but were consistent with the carbon dioxide solubility data measured by the other methods. The micro structure of ionic liquid and molecular liquid mixture was also grasped in detail by NMR measurement and MD simulation. Furthermore, it was found that the absorption liquid flow rate can be reduced by lowering the temperature as a result of constructing the physical absorption model of carbon dioxide.
