| 英文摘要 | Carbon membranes were fabricated through the pre-oxidation and pyrolysis of polyvinyl chloride (PVC). Their chemical composition and structure morphology were characterized using FTIR, SEM and XRD; their CO2 and N-2 adsorption isotherms were measured at 25 degrees C. The experimental results showed that heating rate and holding time have great influences on the pore structure during the pre-oxidation process as well as the carbonization process. The pore structure of the carbon membrane is also influenced by carbonization temperature. The carbon membrane obtained at 700 degrees C has the largest CO2 adsorption capacity of 1.45 mmol/g at 101 kPa. The carbon membrane prepared at heating rate of 3 degrees C/min and holding time of 0.5 h at 800 degrees C displayed an excellent adsorption selectivity of CO2 over N-2 evidenced by the fact that its CO2 adsorption capacity could reach 1.1 mmol/g and while it does not significantly adsorb N-2. |
