본 연구에서는 MEA(monoethanolamine)를 함침한 메조포러스 물질을 이용하여 이산화탄소를 회수하고자 하였다. 이를 위해 MCM-41, MCM-48 및 SBA-15의 메조포러스 물질을 제조한 후 30, 50, 70 wt%의 MEA로 함침하였다. 함침한 메조포러스 물질의 특성을 평가하기 위하여 XRD, FT-IR, SEM, BET를 이용하였다. 이산화탄소 흡탈착 실험을 수행한 결과, 흡착량은 MCM-41>MCM-48>SBA-15 순으로 나타내었다. 최대 이산화탄소 흡착량은 50 wt% MEA 함침 MCM-41으로써 40 ℃에서 57.1 mg-CO2/gr-sorbent이며, 이는 MCM-41과 비교할 때 8배 높았다. 그리고 20회 반복 흡탈착 실험 결과, 반복 실험에도 일정한 흡착능을 나타내었다.
The present study deals with removal of CO2 using various mesoporous materials impregnated with MEA (monoethanolamine). The mesoporous materials such as MCM-41, MCM-48 and SBA-15 were synthesised and then impregnated with 30, 50 and 70 wt% of MEA, respectively. XRD, FT-IR and SEM were used to evaluate the characterization of those. From the adsorption/desorption experiments for various materials, the adsorption capacity of these materials were found in the order of MCM-41> MCM-48> SBA-15. MCM-41 impregnated with 50 wt% of MEA showed the maximum adsorption capacity of 57.1 mg-CO2/gr-sorbent at 40 ℃. It is nearly 8 times higher than MCM-41 without impregnation of MEA. In the multiple cycle test of 20 times, MCM-41 impregnated with 50 wt% of MEA showed a constant adsorption capacity.
