化學迴路程序是一種兼具低成本與高效率之新穎技術，並且可以兼顧環境友善與循環經濟之概念。近年來，隨著台灣之經濟與產業朝向高科技發展，孕育而生的是台灣越來越嚴重之半導體產業有機廢水與電力供應不足之問題。除此之外，台灣之發電越來越倚重以燃燒為主之火力發電，也因此造成嚴重之氮氧化物汙染之問題，也因此對台灣之環境形成嚴苛之考驗。
本研究係在探討化學迴路程序運用於高科技產業之有機廢溶劑丁酮之高溫裂解程序，並期過金屬氧化物載氧體作為觸媒增進其反應之效率，並能夠在後續之實驗中進行脫硝反應。本論文透過XRD、XRF、TGA以及實驗室級半套流體化床，先對鐵礦載氧體與經過參雜氧化錳過後之鐵礦載氧體進行材料組成與丁酮之合成氣產出評估，之後運行脫硝反應以評估其性能。
實驗結果表明，經過錳改質過後之鐵礦載氧體有效強化鐵礦氧化過程中之劣勢，並且運行半套流體化床時，載氧體皆能有效增進丁酮之熱裂解效率，在各個氧化相態可以提升碳轉化率6 - 43.1%不等，此外後之鐵礦載氧體在後續之脫硝性能方面，各個還原相態中，展現優於前之效果，並在實際模擬鍋爐尾氣的條件下可達到最佳之脫硝效果，整體系統之脫硝時間可以達到最長900秒的時間，本實驗最後也進行多次迴圈之連續脫硝實驗，並達到良好之脫硝效果，可供後續實場之運行參考。

Chemical looping process, a novel technology with low cost and high efficiency, can take into environmental friendliness and circular economy. In recent years, as economy and industry of Taiwan have turned into high-tech development, problems of organic wastewater and power supply in the semiconductor industry are getting more serious. Moreover, power generation of Taiwan is increasingly dependent on combustion-based thermal power generation, which has caused serious problems of nitrogen oxide pollution, and therefore has imposed a serious problem on environment of Taiwan.
The purpose of this research is to explore the high-temperature decomposition of the organic waste solvent methyl ethyl ketone used from the high-tech industry by chemical looping process, and the metal oxide is used as a catalyst to improve the efficiency of reaction. After doing decomposition process, oxygen carriers will carry on following process of denitration. In this paper, the material composition of iron ore oxygen carrier and iron ore oxygen carrier modified by doped manganese oxide and synthesis gas of MEK are firstly carried out through XRD, XRF, TGA and laboratory-scale. Denitration were conducted using iron ore and modified iron-ore in a semi-fluidized bed reactor and the results evaluated accordingly.
The experimental results show that the modified iron ore oxygen carrier can effectively strengthen the disadvantages of the iron ore in an oxidation process, and when running half of the fluidized bed, the oxygen carrier can effectively improve the thermal decomposition efficiency from 6% to 43.1%. In addition, in the subsequent denitrification performance of the iron ore carrier after modification, in each reduction phase state, it exhibits a better effect than the raw iron-ore, and can achieve the best desorption under the conditions of actual boiler exhaust gas condition, which can offer 900s non-NOx gas condition in reactor. A multi-round continuous denitration experiment was also carried out, and a good denitration effect was achieved, which can be used as a reference for subsequent real-field operation.
