Evaluation of CO2 adsorption dynamics of polymer/silica supported poly(ethylenimine) hollow fiber sorbents in rapid temperature swing adsorption

- RTSA with polymer/silica supported PEI hollow fiber sorbents for CO2 capture.
- Effect of conditions on dynamic adsorption/desorption performance evaluated.
- Hollow fiber sorbents exhibit good cyclic stability over 60 cycles.
- Post-spinning amine infusion technique recharges deactivated sorbents with PEI.
