| Abstract |
In this study, we synthesized two types of mesoporous silica materials for use as supports to amine-impregnated for CO2 capture. One was mesoporous silica sphere (MSS) materials and the other was mesoporous hollow silica materials (MHSS). MHSS and MSS were synthesized and modified by wet impregnation with tetraethylenepentamine (TEPA) as solid adsorbents. MHSS materials were synthesized from core-shell structured polystyrene(PS) core with mesoporous silica shell. The prepared solid adsorbents were characterized by TEM, XRD, N2 adsorption/desorption, FT-IR, and TGA and their CO2 capture capacity was tested. The CO2 capture performance of the adsorbent was evaluated by the gap in the CO2 concentration of the influent and effluent gas streams at atmospheric pressure. We investigated the influence of the loaded TEPA amount on the CO2 capture performance. An increase in the amount of loaded TEPA, improved the CO2 adsorption capacity of the prepared adsorbents. In addition, we compared the CO2 capture performance with the use of two types of silica materials as supports. Due to the excellent structural properties of the MHSS, MHSS is better than MSS as amine support. |
