Abstract: We synthesized the sterically hindered amine A by an appropriate placement of alkyl groups. Quantitative 13C NMR spectroscopy was performed on 30 wt% aqueous solution of the amine A with different amount of CO2 at 40°C. The results suggested that the amine A only formed the carbonate anion in this system. Performance evaluations of the absorbent-A containing the amine A were carried out based on their CO2 absorption rate, absorption capacity and heat of reaction measurements. The absorbent-A containing the amine A showed high absorption capacity and high absorption rate and relative low heat of reaction compared to 30 wt% MEA solution. The absorbent-A has been selected for further tests in the bench- scale apparatus. We will evaluate the absorbent-A at Mikawa pilot plant (10 ton/day) owned by TOSHIBA, using the actual flue gas from Mikawa coal fired power plant in Fukuoka prefecture, Japan.
