Synthesis of polyehthyleneimine-modified titanate nanotubes for CO2 capture under flue gas condition |
| 초록 |
. In this work, we have prepared titanate nanotubes (TNT) with amine modification using polyethyleneimine (PEI) for selective carbon dioxide (CO2) capture under flue gas condition. TNTs have prepared by hydrothermal reaction, and PEI-functionalized TNT (P-TNT) have prepared by wet impregnation method. Enhanced CO2 affinity through amine modification on TNT allow for selective and favorable CO2 adsorption onto adsorbents. The multi-component CO2 adsorption performances were investigated by the gravimetric method under flue gas (15% CO2 in N2 as gas condition in fossil fuel power plants). Th optimized samples with highest CO2 uptakes for CO2/N2 (15:85) gas mixture of 44.5 mg/g are attained at 313 K. This result suggests that P-TNT is a promising adsorbent for the challenges of current CO2 capture and separation technologies and can provide a development strategy for amine-modified adsorbents. |
