Abstract

This study reports a preparation method of a new moisture swing sorbent for CO₂ capture from air. The new sorbent components include ion exchange resin (IER) and polyvinyl chloride (PVC) as a binder. The IER can absorb CO₂ when surrounding is dry and release CO₂ when surrounding is wet. The manuscript presents the studies of membrane structure, kinetic model of absorption process, performance of desorption process and the diffusivity of water molecules in the CO₂ absorbent. It has been proved that the kinetic performance of CO₂ absorption/desorption can be improved by using thin binder and hot water treatment. The fast kinetics of P-100-90C absorbent is due to the thin PVC binder, and high diffusion rate of H₂O molecules in the sample. The impressive is this new CO₂ absorbent has the fastest CO₂ absorption rate among all absorbents which have been reported by other up-to-date literatures.
