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.

该项目开发了一种新的异丙基官能化多胺（IPFPA）基非水溶剂（NAS），用于从燃烧后烟气中回收CO2，这将显著提高CO2捕集性能，同时降低溶剂再生能量。本项目共合成了10个新的（第二代）IPFPA，纯度高（>98%），产率高（>96%）。NAS系统通过混合作为吸收剂的IPFPA和作为溶剂的市售醇/非醇来制备。去年完成了所有合成多胺的优化。今年完成了5种醇溶剂和5种非醇溶剂的筛选实验，获得了最佳IPFPA性能。异丙基功能化多胺IP-DMDPTA被确定为最佳多胺，1-甲基咪唑（1 MIm）被确定为最佳有机溶剂。对（IP-DMDPTA+1 MIm）NAS进行了优化，全面测试了各种相关性能，并确定了其最佳组成，使其具有高CO2吸收率，高CO2循环量，消耗最少的热能。
