evaluation of modified polyurethane nanofibers with ethanol amine for co2 adsorption

Recently, the need for new co2 adsorbents with high adsorption capacity and stability has been incresed. nanofiber adsorbents are one of the materials that can be used in this application. in this study, polyurethane (pu) nanofiber adsorbents were prepared by electrospinning and then modified with ethanolamine (ea). carbon dioxide adsorption experiments were performed in a fixed-bed column with a mixture of co2/n2 in (5-10-15%) of co2 . the adsorption capacity of modified pu adsorbent with 60% ea concentration at 10% co2 concentration had the highest adsorption rate. also, it shows the high stability of pu adsorbent after four cycles of adsorption-desorption procedure.
