Olefin/paraffin separation membranes have been interested due to many advantages such as low cost and simple operation. The long-term stability, high selectivity for olefin/paraffin, and high permeance have been required for the practical applications of facilitated olefin transport membranes. Previous results obtained for membranes consisting of poly(2-ethyl-2-oxazoline) (POZ), AgBF4, and Al(NO3)3 showed relatively low mixed-gas permeance, i.e., 4.8 GPU, even though these membranes have excellent long-term stability. In this study, poly(ethylene oxide) (PEO) was suggested as a new polymer matrix for practical applications. We found that when PEO was utilized as the polymer matrix, the membrane showed long-term stability and the mixed-gas permeance increased to 20 GPU. It was thought that this enhanced performance was attributed to the stabilization of silver ions in the permeable polymer matrix. |
