本研究是以Nafion117陽離子交換薄膜作為滲透蒸發之用,針對苯與環己烷系統利用銀離子與不飽和雙鍵的錯合作用,達到苯與環己烷分離的目的。探討不同的薄膜前處理與各操作條件對於滲透蒸發效果的影響,更進一步探討苯與環己烷在滲透蒸發的質傳模式。
結果顯示,在經過不同薄膜前處理方式的比較,以NaOH處理,再由硝酸銀甘油膨潤後的Nafion薄膜,其銀含量較高,約為17%,而以此薄膜做滲透蒸發實驗,對於本系統其選擇比可達14.6。
在蒸氣吸附動力結果,苯的擴散係數約是環己烷的兩倍。環己烷之擴散係數為9.36‧10-14m2/s∼2.53‧10-13m2/s,苯之擴散係數為1.87‧10-13m2/s∼3.50‧10-13m2/s;平衡吸附量的吸附等溫線以Flory-Huggins equation迴歸得環己烷的χ值為1.97,苯的χ值為1.305。在液體吸附實驗中,在Ag+-Nafion薄膜內,苯的吸附量均大於環己烷。對純溶劑吸附而言,在銀型薄膜中,苯的χ值為1.57,環己烷為2.28。在鈉型薄膜中苯的χ值為2.096,環己烷為2.89。液體吸附實驗顯示苯或環己烷的吸附量深受另一溶劑存在的影響,在同一活性下,均較蒸氣的吸附量多,且苯的吸附等溫線的模式也接近於Langmuir形式。
在滲透蒸發實驗,當進料苯的濃度增加,苯的流通量隨之呈線性增加,而環己烷則減少。且當操作溫度25℃時,其選擇比亦隨進料苯的濃度增加而呈線性增加。當操作溫度上升時,苯及環己烷的流通量皆增加,但選擇比卻下降。當下游壓力增加時,其流通量與選擇比皆呈明顯下降的趨勢。在Na+-Nafion薄膜滲透蒸發實驗結果顯示鈉離子對於苯/環己烷系統無選擇性,與Ag+-Nafion薄膜比較,更可證實以銀離子作介質的輔助輸送,對於分離的確有顯著的效果,亦可證明,銀離子對於芳香族有其選擇特異性。
The objective of this study was to separate benzene from cyclohexane by pervaporation membranes containing silver ion. The “ Nafion 117 ” membrane is a cation-exchange membrane in nature and the silver group can form complex with the double bonds in benzene.The effect of the membrane condition methods and the operating conditions on pervaporation were studied. Furthermore, the sorption isotherms of benzene and cyclohexane on Ag+-Nafion membrane were established and the diffusivity coefficients were determined.
The membrane pretreated with NaOH and exchanged with silver ion in glycerol had greater exchenge capacity and result in higher flux in pervaporation process. A selectivity of 14.6 was obtained on pervaporation of 75/25 mixture (Vbenzene / Vcyclohexane).
In the vapor sorption experiments, the diffusivity coefficient of cyclohexane is 9.36‧10-14m2/s∼2.53‧10-13m2/s and benzene is 1.87‧10-13m2/s∼3.50‧10-13m2/s. In Ag+-Nafion membrane, the sorption behavior could be adequately described by Flory-Huggins equations (χcyclohexane=1.97±0.559,χbenzene=1.305±0.134). In the liquid sorption experiments,the solvent uptake was in the order : benzene>cyclohexane. In Ag+-Nafion membrane,χcyclohexane=2.2776,χbenzene=1.5688.In Na+-Nafion membrane,χcyclohexane=2.0956,χbenzene=2.8866.
The liquid sorption of the solvent was influenced by the presence of a second solvent. The sorbed amount was higher than that of vapor at the same solvent activity. Besides, the sorption behavier of benzene solvent was distinct from the vapor sorption and showed a Langmuir sorption model.
In the pervaporation experiments, the flux increased with increased feed concentration.and increased temperature, but the selectivity reduced with increased temperature. Both flux and selectivity reduced with increased down stream pressure.
