本研究之主要目的，以濕式造粒法改善載氧體制備流程，並評估所製備的載氧體之物理及化學性質，濕式造粒法為工業上於量產時常用之手段，以此法可製備得球型顆粒之載氧體，以減少載氧體於反應器間流動時所造成的磨耗損失，並於各項物理性及化學性質測試可知各項性質均已被優化改善。鐵系載氧體同時添加氧化鋁及氧化鈦兩種擔體，可製備得結合鐵鋁及鐵鈦兩種載氧體之優勢，發展出更有前瞻之材料，於各項測試中顯示鐵鋁鈦之各評估指標介於鐵鋁及鐵鈦之間。製備而得之鐵係載氧體應用於架設移動床式蒸氣反應器之化學迴路產氫程序之可行性評估。移動床蒸氣反應器系統是由移動床式蒸氣反應器與載氧體輸送單元組成，水蒸氣由自來水以注射幫浦進行進料。移動床式蒸氣反應器性能測試部分，以還原態鐵鋁載氧體在移動床式蒸氣反應器中於800-900oC下通入蒸氣進行氧化產生氫氣，當提供足量之蒸氣時可獲得較大之產氫量及載氧體轉化率，可以在長時間連續操作下達約1400 ml-H2/min之氫氣產生及82.11 ml-H2/g-OC之產氫量。以還原態鐵鋁鈦載氧體在移動床式蒸氣反應器中於800-900oC下通入蒸氣進行氧化產生氫氣，結果鐵鋁載氧體比較具有較佳之產氫量85.99 ml-H2/g-OC，然仍需克服載氧體於反應器管壁燒結團聚之現象。

The oxygen carrier plays a key point in CLHG process, for the future development, wet granulation process was adopted for preparing oxygen carrier, the process could prepare sphere oxygen carriers to decrease the attrition and increase crush strength. Iron-based oxygen carrier supported on Al2O3 and TIO2 was evaluated. The results showed that the oxygen carrier could have the advantage of iron-based oxygen carrier supported on TiO2 or Al2O3.
A moving bed steam reactor system for chemical looping hydrogen generation with FA323-S1 and FAT7212-S0 oxygen carrier was developed and operated. The system composed of a moving bed steam reactor with oxygen carrier and fuel transportation units. The moving bed steam reactor system was successfully set up and operated using FA323-S1 and FAT7212-S0 oxygen carriers. However, the FAT7212-S0 oxygen carrier showed agglomeration issue in each experiment, hence, the reactor must be modified for successfully operating the system with FAT7212-S0 oxygen carrier. The quality of hydrogen generation on FA323-S1 and FAT7212-S1 oxygen carriers was 82.11 and 85.99 ml-H2/g-OC during the CLHG process test, respectively. It showed that FAT7212-S0 was a potential material in CLHG process. Long-term integrity test was carried out in the moving bed steam reactor for generating hydrogen. A steady hydrogen production rate was achieved for FA323-S1-S oxygen carrier, and the experiment was continuously run with more than 6 hours.
