胺基酸鹽被認為具有和CO2良好的反應性、低蒸氣壓、熱穩定性、低氧氣劣化性、環境友善及生物可分解性等優點，是新一代具潛力的吸收劑，因此本研究從胺基酸鹽中篩選出具有潛力的吸收劑進行CO2吸收及再生的探討，並以實驗室發展之超重力旋轉床技術(Higee Technology)取代傳統吸收塔，以縮小設備體積並增加質傳係數KGa，使吸收劑更能有效捕獲CO2。
RPB吸收實驗結果顯示，PZ/DETA/Na ADS(15 wt%/15 wt%/10 wt%)吸收劑黏度較PZ/DETA (15 wt%/15 wt%)高1.48倍，雖然黏度增加會降低CO2於吸收劑中之擴散係數及增加CO2於吸收劑中之亨利常數，但是此時自由胺基數是多於PZ/DETA (15 wt%/15 wt%)，且藉由RPB填料區的高速旋轉提供之高剪切力，可將吸收劑切割及分散以減少因黏度造成的負面效應，所以在CO2捕獲效率及KGa方面， PZ/DETA/Na ADS(15 wt%/15 wt%/10 wt%)吸收劑配方與PZ/DETA (15 wt%/15 wt%)表現相似。
RPB吸收與再生連續操作實驗結果顯示，在2atm、120 oC下相較於30 wt% MEA，PZ/DETA/Na ADS(15 wt%/15 wt%/10 wt%)吸收劑配方之再生能耗可減少8.8%。因為PZ及DETA吸收劑之反應熱及比熱皆較30 wt% MEA為低，且吸收劑濃度較高可減少部分蒸發熱，在後續的50oC RPB吸收實驗中PZ/DETA/Na ADS(15 wt%/15 wt%/10 wt%)吸收劑配方在CO2捕獲量方面可較30 wt% MEA提升22.6%，可處理較多的氣體量。
綜合各吸收劑配方吸收效果、再生能耗與氧氣溶解度之比較，本研究所提出之PZ/DETA/Na ADS(15 wt%/15 wt%/10 wt%)吸收劑配方實為一具有發展潛力之吸收劑。

Amino acid salts are of great interest as potential solvents for CO2 capture because they are considered have a relatively fast rate of CO2 absorption, less volatile, higher stability towards oxygen and thermal and environmentally friendly. This research aims to find out the potential amino acid salt as absorbent primarily by investigating their absorption and desorption performance, and to apply the potential absorbent in rotational packed bed (RPB). Compared with traditional packed bed (PB), the rotational packed bed could provide higher KGa, and have smaller equipment volume, which could further increase the capture efficiency.
The experimental results show that the viscosity of PZ/DETA/Na ADS (15 wt%/15 wt%/10 wt%) is 1.48 times the viscosity of PZ/DETA(15 wt%/15 wt%). Although the higher viscosity could lower the diffusion coefficient, and increase the Henry constant of CO2 in absorbent, but the amount of free amines in PZ/DETA/Na ADS (15 wt%/15 wt%/10 wt%) is more than the ones in PZ/DETA(15 wt%/15 wt%). Also, he absorbent could be split into small drops and well-dispersed with the shear stress of RPB, and this could further reduce the viscosity effect. As a result, PZ/DETA/Na ADS (15 wt%/15 wt%/10 wt%) has similar capture performance as PZ/DETA(15 wt%/15 wt%).
The RPB continuous operations of absorption and desorption results show that under 2 atm 120 oC situation, the PZ/DETA/Na ADS (15 wt%/15 wt%/10 wt%) could be regenerated with 8.8% lower energy than conventional absorbent 30 wt% MEA. This is because that the reaction energy and sensible heat of PZ and DETA are both lower than the ones of MEA, and it also had high CO2 capture efficiency.
PZ/DETA/Na ADS (15 wt%/15 wt%/10 wt%), as the most promising absorbent, could be regenerated with lower energy than conventional absorbent 30 wt% MEA, and it also had high CO2 capture efficiency and CO2 capacity. Besides, DO value in the formula is lower, so it can reduce the corrosion.
