Gas transport and separation through alumina membranes coated by Polyphenylene oxide (PPO) polymers |
| 초록 |
Interests on membrane processes for gas separation using ceramic membranes have considerably increased in many application areas because of thermal, chemical and mechanical stabilities. In this study, the composite ceramic membranes were prepared on the α-alumina support with the pore size of 90 nm. The surface of the α-alumina ceramic membranes were modified with poly (2,6-dimethyl-1,4-pyphenylene oxide) (PPO), which is known to have high gas permeability among aromatic polymers. In addition, the composite alumina membrane was prepared with sulfonation and metal substitution of PPO. The properties of the separation and the transport of gas components were investigated using weakly adsorbing components (He, N2, and CH4) and strongly adsorbing components (CO2 and C2H6). It was observed that sulfonation and metal substitution of PPO polymer could increase gas permeation performance, and that the permeation performance of adsorbing gas components was larger due to a pillar effect on the polymer structure. It was shown through the gas transport experiments that the modified alumina ceramic membranes could be used for industrial applications in ambient temperature and moderate pressure difference. |
