Abstract

Amine-loaded silica/poly(amide-imide) hollow fiber sorbents are created and used for CO2 capture under simulated post-combustion flue gas conditions. Amine is infused into the mesoporous silica/ poly(amide-imide) hollow fiber sorbents during fiber solvent exchange steps after fiber spinning. The amine loaded fibers are tested by exposure to simulated flue gas at 1 atm and 35 °C The amine functionalized mesoporous silica / poly(amide-imide) hollow fibers comprising ~5 wt% silica with a high CO2 equilibrium capacity of 1.8 mmol/g-fiber which is significantly higher than previously reported for fiber sorbents.
