dc.description.abstractIn order to prevent 14% of carbon emissions over 50 years, 90% of the world's coal-fired power plants will require a CO2 capture system. But there is a problem of scale. In CO2 capture field, porous solid sorbents need low energy for the CO2 recovery and have low heat capacity. Especially, metal organic frameworks (MOFs) as solid sorbents are attracting attention as materials which have not only a high specific surface area due to its microporous property, but also have an excellent CO2 adsorption capacity because due to its open metal sites. Although Mg2(dobdc) MOF which is one of the top performing MOFs has 8 mmol/g @ 298K and 1 bar, the MOF encounters the bottle-neck of loss capacity to 80% under humid conditions. Recently, supported amine adsorbents are effective for CO2 capture at low CO2 partial pressures and can be stabilized in water via decoration on the open metal site of MOFs. In addition, hollow fiber can possess high loading of adsorbent and good mass transfer rate, as well as realize scalability and cost efficiency. In this study, using a two-step processes such as spinning and post-spinning, we have successfully synthesized the mmen-Mg2(dobdpc) MOF fiber sorbents from magnesium oxide (MgO) fiber sorbent precursors. We demonstrated the material property and performance of the sample by XRD, SEM, BET, and CO2 sorption test under various conditions.-
