초록

기-액 흡수 평형장치에서 이온성액체와 아민수용액의 이산화탄소 흡수특성을 평가하였다. 9가지의 이온성액체와 두 종류의 아민수용액의 이산화탄소 압력에 따른 흡수특성과 시간에 따른 흡수속도를 측정하였다. 이온성액체의 양이온과 음이온을 변화시켜 이산화탄소흡수에대한 이온의 영향을 알아보았다. 아민수용액은 이온성액체보다 높은 이산화탄소 흡수능과 빠른 흡수속도를 보였다. 이온성액체 중에서는 1 bar에서 $0.14molCO_2/molIL$의 흡수능을 보인 [emim][$Tf_2N$]이 가장 우수한 효율을 보였다. 흡수반응온도가 증가할 수 록 이산화탄소 흡수능은 급격한 감소를 보였다. 이산화탄소 흡수에는 이온성액체의 음이온이 주된 역할을 수행하며 양이온은 부가적인 역할을 수행하는 것으로 판단된다.

The solubility of carbon dioxide in ionic liquids and amine solvents has been investigated in gas-liquid absorption equilibrium reactor. Absorption capacity and kinetics of $CO_2$ with $CO_2$ pressure and absorption time in 9 different ionic liquids and 2 kinds of amine solvents were evaluated. In order to understand the effect of ionic type, we changed the cation or anion of ionic liquids. $CO_2$ absorption capacity and absorption rate of amine solvents were higher than those of ionic liquids. $CO_2$ absorption capacity of [emim][$Tf_2N$], $0.14molCO_2/mol\;IL$ at 1 bar, was the highest among the ionic liquids. $CO_2$ absorption capacity of ionic liquid steeply decreased with increasing temperature. Anion of ionic liquid dominates interaction with $CO_2$ and cation plays secondary role.
