化學迴路燃燒程序為一種低成本、高能源效率、環境友善又有高二氧化碳捕獲率的新穎燃燒技術，其關鍵就在名為「載氧體」的一種金屬氧化物陶瓷粉末觸媒上。其中錳系載氧體價格低廉且反應性優良，其選擇亦可為易取得之天然礦石或是工業廢棄物，為目前最具潛力之載氧體選擇，而生活中，廢棄乾電池裡就蘊含了大量的錳元素，將可以作為載氧體的最佳材料。
因此本研究以乾電池之廢棄氧化錳與氧化鐵載氧體進行整合，使其作為新穎載氧體原料並應用化學迴路燃燒程序，以複合型載氧體之形式改良目前最廣被應用的鐵系觸媒，搭配XRD、TGA、SEM、實驗及半套式流體化床等實驗儀器，先評估回收乾電池氧化錳之材料組成以及熱學性質，再以氧化錳模擬乾電池粉末混合氧化鐵載氧體進行調配分析以及操作測試，最後再以實際乾電池粉末與氧化鐵進行複合型載氧體之合成，評估回收乾電池氧化錳用於化學迴路燃燒程序中之可行性。
本研究最終測得回收乾電池氧化錳與Mn3O4有著相似性質，是可以做為鐵錳複合載氧體之材料之一，並得出氧化鐵/氧化錳複合型載氧體以有兩相互存的F7M3之鐵錳比例參數有著最優異的反應性性能以及抗團聚能力，但當以此比例實際以乾電池氧化錳取代純錳金屬氧化物時卻出現了鋅鐵氧化物之問題，導致反應性降低以及不耐磨耗等現象，即使如此，仍在其中發現鋅的存在使錳可以大量的固溶進氧化鐵，使原本不具釋氧能力之赤鐵礦結構亦出現釋氧之現象。

The chemical loop combustion process is a novel combustion technology with low cost, high energy efficiency, environmental friendliness and high carbon dioxide capture rate. The key is the catalyst metal oxide ceramic powder called "oxygen carrier". However, manganese-based oxygen carriers are inexpensive and have good reactivity. They can also be selected as natural ores or industrial wastes, which are the most potential oxygen carriers. In our life, waste batteries also include a large amount of manganese will be used as the best material for the oxygen carrier.
Therefore, in this study, the iron oxide and manganese oxide of the dry cell battery were integrated into a novel oxygen carrier material for chemical looping combustion program was applied to improve the most widely used iron system oxygen carrier. Use XRD, TGA, SEM, lab-scaled semi-fluidized bed reactor and other experimental instruments will first evaluate the material composition and thermal properties of the dry cell battery manganese oxide, and then mix the manganese oxide simulated dry battery powder with iron oxide as oxygen carrier to doing analysis and operation test. Finally, the synthesis of composite oxygen carrier by actual dry cell battery powder and iron oxide will be evaluate the feasibility of chemical looping combustion process.
In this study, it was finally determined that the recovered dry battery manganese oxide has similar properties to Mn3O4, and it can be used as one of the materials of iron-manganese oxygen carrier. The F7M3 iron-manganese oxygen carrier is obtained to have two mutually existing, so this iron-manganese ratio parameter has the most excellent reactivity and anti-agglomeration ability, but when the ratio of actual manganese oxide is replaced by dry battery manganese oxide, the problem of zinc-iron oxide appears, it will result a decrease in reactivity and attrition resistance. Even so, the presence of zinc allows the manganese to be solid-dissolved into the iron oxide in a large amount, so that the hematite structure which does not have the ability to release oxygen also exhibits oxygen release.
