| Outline of Final Research Achievements |
CO2 capture and storage technology (CCS) attracts attention as CO2 reduction is required as a measure against global warming. In this laboratory, energy conservation is considered by introducing the concept of phase separation type absorbent in chemical absorption method suitable for exhaust gas generated on a large scale at normal pressure. The phase separation type absorbent is a novel chemical absorbent which separates into two liquid phases after absorbing carbon dioxide by adding an additive to the amine type solution. In this study, we examined two points: (1) acquisition of phase equilibrium data of chemical absorbent that separates into two liquid phases after absorption of CO2, and (2) comparison of relative absorption rates of various CO2 absorbents. The phase separation type absorbent revealed that it can absorb and regenerate with a low temperature difference and the absorption rate is also high.
