本研究探討導離子氧化物薄膜反應器(membrane reactor)製作，藉以分析導離子薄膜對於中溫甲烷產氫以及CO2脫氧反應的助效作用。薄膜反應器製作部分，包含設計與部件材料選擇，再檢驗反應器的氣密性，當以高溫陶瓷膠環狀固定膜材，發現管壁粗糙度會影響薄膜封裝氣密性。研究比較觸媒在三種不同反應系統(玻璃填充床反應器、非導離子陶瓷薄膜反應器與導離子薄膜反應器)的反應效能，分別探討GDC(Gd-doped CeO2)導氧離子薄膜對CO2脫氧反應的助效，以及SCZY(Sr(Ce0.6Zr0.4)0.8Y0.2O3-δ)導氫離子薄膜對甲烷蒸氣重組反應的助效，研究結果顯示自製薄膜反應器中觸媒的還原特徵與反應特徵與玻璃填充床反應器中特徵一致。Ce3Fe7Ox觸媒搭配GDC薄膜系統的CO2脫氧的效能提升約50%，顯示GDC薄膜的導氧離子特性能助效觸媒反應。另嘗試施加電場測試薄膜離子傳導性提升觸媒反應的影響，結果顯示在Ce3Fe7Ox觸媒反應活性終止後施加電場對CO2脫氧反應並無再提升的作用，但此測試也可能受到反應器薄膜二側阻抗過大所影響。在SCZY薄膜對Ni/LZC觸媒觸媒催化甲烷蒸氣重組反應的探討，結果顯示SCZY薄膜會提升500°C下甲烷轉化率，並不會造成積碳現象或顯著改變CO生成選擇率。在薄膜反應器施加電場對穩態操作下的甲烷轉化率並沒有明顯提升。

This study explores membrane reactors enhancement by ion-conducting membrane on the catalytic reaction of steam reforming of methane and oxygen stripping of CO2, separately the fabrication of membrane reactor is firstly discussed, including design and component material selection, gas leak proof check for confirming the design. The membrane is fixed in place using ceramic adhesive. It is found that the tube wall roughness will affect the sealing of membrane. We compare the reaction efficiency of catalysts in three different reaction systems (packed bed glass reactor, membrane reactor with ceramic non-porous membrane and with ion-conducting membrane reactor), to identify the effect of GDC (Gd-doped CeO2) oxygen ion conducting membrane on oxygen stripping of CO2 and the effect of SCZY (Sr(Ce0.6Zr0.4)0.8Y0.2O3-δ) hydrogen ion conducting membrane on steam reforming of methane. The results show that the catalyst in different system show the same reduction characteristics. The Ce3Fe7Ox catalyst combined with GDC membrane system can have approximately 50% increase efficiency of oxygen stripping of CO2, which shows that the oxygen ion-conducting characteristic of GDC membrane enhance the catalyst reaction. A further attempt by applying an electric field across the ion conducting membrane cannot promote the catalytic reaction after the Ce3Fe7Ox catalyst reaction activity terminated. However, this test results may be affected by the excessive impedance across the membrane. The Ni/LZC catalyst combined with SCZY membrane system is also formed to increase methane conversion at 500°C without coking or significantly changed CO selectivity. The application of an electric field in the membrane reactor does not further improve the methane conversion under steady-state operation.
