Abstract: |
|
In this study, the effect of silica nanoparticles on the gas permeation properties of polyethersulfone gas separation membrane was investigated. The membranes’ microstructure, mechanical properties and gas separation performance were investigated by SEM, tensile tester and gas separation experiment. The results showed that Young’s modulus of PES-SiO2 hollow fiber membranes and permeation fluxes of H2, N2, O2, CH4 and CO2 increased whereas separation factors of O2/N2, CO2/CH4 and H2/N2 decreased with the increase of SiO2 contents. The hollow fiber membranes tended to stable after the testing period of 16 days. When the membranes were treated by ethanol and n-hexane as exchange agent, dried in the oven, the membranes had a better selectivity. |
