摘要

Abstract

Fixed carrier membrane exhibits attractive CO

permeance and selectivity due to its transport mecha-nism of reaction selectivity (facilitated transport). However

its performance needs improvement to meet cost targets for CO

capture. This study attempts to develop membranes with multiple permselective mechanisms in order to enhance CO

separation performance of fixed carrier membrane. In this study

a novel membrane with multiple permselective mechanisms of solubility selectivity and reaction selectivity was developed by incorporating CO

-selective adsorptive silica nanoparticles in situ into the tertiary amine containing polyamide membrane formed by interfacial polymerization (IP). Various techniques were employed to characterize the polyamide and polyamide-silica composite membranes. The TGA result shows that nanocomposite membranes exhibit superior thermal stability than pure polyamide membranes. In addition

gas permeation experiments show that both nanocomposite membranes have larger CO

permeance than pure polyamide membranes. The enhanced CO

separation performance for nanocomposite membranes is mainly due to the thin film thickness

and multiple permselective mechanisms of solubility selectivity and reaction selectivity.
