dc.description.abstract | 本研究利用親水性佳的PVA (polyvinyl alcohol)高分子為主體刮製在PSf (Polysulfone)基材將其製備成複合薄膜,藉由添加劑改質以開發高性能氣體分離膜,期望進行輸送傳輸機制(facilitated transport)來提升CO2的透過量,並且添加可和CO2間產生良好親和性的醚基分子以及可發生輸送傳輸機制的胺基分子,進一步提升CO2分離效能,文獻中也提及水氣在CO2分離過程中扮演著重要的角色,使水分子、胺基分子及CO2三者反應形成錯合物可減少胺基的消耗量,提升攜帶CO2的數目以增加透過量,於是探討在操作的環境中有水氣和沒水氣對CO2分離效能所產生的影響。
實驗結果顯示出薄膜在相同組成下在操作環境中含有水氣時其CO2透過量以及選擇性皆高於不含水氣時系統,因此可得知水氣在分離CO2過程中是重要的影響因素。另外,若在含有水氣時的系統下操作並且添加含醚基的Polyethylene glycol(PEG)分子,CO2透過量可由未添加前的21GPU上升至40GPU左右。然而添加胺基分子時,尤其在Branched polyethylenimine(BPEI)的條件下,薄膜表面變得更為親水其表面接觸角由原本的39°下降至25°左右,且薄膜吸水性測試高達104%,水份可讓消耗的胺基變少以增加攜帶CO2的數目,且隨著胺基的添加濃度增加,選擇比也有大幅的提升CO2透過量在31.7GPU時選擇比可以高達546,主要造成此結果是由於在有水氣的環境下可以減少胺基消耗量以提高攜帶CO2數目,並且N2對水的溶解度低造成透過的阻礙,因此當薄膜內的水份增加,使N2透過量大幅的下降,可以得到高選擇比。 | zh_TW |
dc.description.abstract | According to this study, by using Polyvinyl alcohol(PVA) as selected layer to cast on Polysulfone(PSf) substrate in terms of preparing composite membrane, and to modify the membrane by using additive agents to develop high performance on gas separation. By using facilitated transport mechanism to improve carbon dioxide flux, and using carrier combining with carbon dioxide to improve facilitated transport in progress. It was mentioned in record that water plays an important role in carbon dioxide separation process. Regarding to the amino group, water molecular reacts with amino group and carbon dioxide to produce complex so that the amino group consumption is decreased and increase the amount of carbon dioxide to carrier and increase flux. Therefore, we are studying how the water in the environment will affect the separation process.
The results of experiment show that the membrane, under the condition of same composition, and environment without water, permeation and selectivity of carbon dioxide is less than the environment with water. So we can learn that water is an important factor on carbon dioxide separation process. When operating in the environment of water, carbon dioxide flux will increase from 21 GPU to 40 GPU when adding the molecular Polyethylene glycol which includes ether group. In addition, by adding the molecular which includes amino group will increase carbon dioxide performance obviously, especially in the condition of additive Branched Polyethylenimine(BPEI), It became more hydrophilic and the contact angle decreased from 39 degree to 25 degree. We can also learn that membrane’s water content is 104%, so the consumption of amino group is decreased and the carry of carbon dioxide is increased. Along with the increase of the concentration of amino group, the selectivity has obvious improvement that when the carbon dioxide flux is 31.7 GPU, the selectivity can get up to 546. The main reason is nitrogen has low solubility with water cause barrier to permeation, so nitrogen flux decrease serious follow the water content increase in the membrane, due to this reason, it can get high selectivity. | en |
