| 研究実績の概要 |
This project, new isopropyl-functionalized polyamine (IPFPA) based non-aqueous solvent (NAS) was developed for the recovery of CO2 from post-combustion flue gases that will achieve a significant increase in CO2 capture performances with a reduction of solvent regeneration energy. A total of 10 new (Generation II) IPFPA(s) was synthesized with high purity (>98%) and excellent yield (>96%) during this project. The NAS system was made by mixing IPFPA as absorbent and commercially available alcohol/non-alcohol as solvent. Last year the optimization of all synthesized polyamine completed. This year 5 alcohol solvents and 5 non-alcohol solvents screening experiments was completed with the best IPFPA performer. Isopropyl functionalized polyamine IP-DMDPTA was identified as best polyamine and 1-methylimidazole (1MIm) was identified as best organic solvent. (IP-DMDPTA+1MIm) based NAS was optimized, thoroughly measuring all relevant properties, and identified their best composition which give high CO2 absorption rate, high cyclic amount of CO2, and consume the minimal amount of heat energy.

理由
The applicant completed (IP-DMDPTA+1MIm) based NAS the composition optimization thoroughly measuring all relevant properties, and identified their best composition which give high CO2 absorption rate, high cyclic amount of CO2, and consume the minimal amount of heat energy compared to benchmark monoethanolamine (MEA). Now efforts are given the bulk scale synthesis of IP-TMDPTA to perform vapor-liquid equilibrium (VLE) experiment under equilibrium condition at different temperature and pressure in order to obtain maximum working capacity. These findings were submitted as a Japanese patent application and presented in two international conferences.

| 今後の研究の推進方策 |
Finalize (IP-DMDPTA+1MIm) based NAS vapor-liquid equilibrium (VLE) experiment under equilibrium condition at different temperature and pressure in order to obtain maximum the working capacity. 13C NMR spectroscopic technique will be used to analyze (IP-DMDPTA+1MIm) based NAS CO2-loaded solutions species identification. Finally conduct bench-scale test, finalize systems and economic analyses, and develop a path forward for bench-scale and pilot-plant testing.

| 次年度使用額が生じた理由 |
The outsourcing chemicals price is higher than the remaining fund. As a result, the relevant chemicals purchase for IP-DMDPTA synthesis was delayed. The bulk scale (kg level) IP-DMDPTA synthesis specific chemicals will be purchasing this FY by adjusting the remaining fund.
