摘要：
Aqueous solution containing sterically hindered amine represents candidate solvents having good potential for carbon dioxide (CO2) capture. In the present work, the CO2 reaction with amine-X having sterically hindered substituents in aqueous solution (absorbent-X) is investigated by laboratory scale apparatus. Absorbent-X was found to have the high CO2 cyclic capacity and the low CO2 release temperature. Furthermore, the CO2 regeneration energy of absorbent-X was 45% less than that of general 30 wt% MEA aqueous solution. We will evaluate the absorbent-X at Mikawa pilot plant (10 ton-CO2/day recovery) owned by Toshiba Corp. using the actual flue gas from Mikawa coal fired power plant in Fukuoka prefecture, Japan.
