摘要

Abstract

Membrane technology features inspiring excellence from numerous separation technologies for CO

capture from post-combustion gas. Polyvinylamine (PVAm)-based facilitated transport membranes show significantly high separation performance

which has been proven promising for industrial scale-up. However

commercialized PVAm with low molecular weight and excessive crystallinity is not available to prepare high-performance membranes. Herein

the synthesis process of PVAm was optimized by regulating polymerization and acidic hydrolytic conditions. The membranes based on PVAm with a molecular weight of 154 kDa and crystallinity of 11.37% display high CO

permeance of 726 GPU and CO

selectivity of 55 at a feed gas pressure of 0.50 MPa. Furthermore

we established a PVAm synthesis reactor with an annual PVAm solution (1%(mass)) capacity of over 7000 kg and realized the scaled-up manufacture of both PVAm and composite membranes.
