Adsorptive removal of carbon dioxide using polyethyleneimine loaded glass fiber in a fixed bed

- Polyethyleneimine (PEI)-loaded Glass Fiber was successfully prepared.
- PEI-loaded GF with core-shell structure performed well on CO2 adsorption.
- The optimum condition for CO2 adsorption in a fixed PEI-loaded GF bed was obtained.
- The regeneration temperature should be around 100 °C with RH lower than 30%.
- PEI-loaded GF showed good cyclic CO2 adsorption-desorption performance.
