藉由渦輪機出口氣體的廢熱(約500 ℃)，配合甲烷/二氧化碳重組的概念，進行引擎出口氣體二氧化碳回收的可行性研究，希望能一舉達到廢熱回收與二氧化碳減量的目標。
利用電熱與流量控制設備模擬前端渦輪引擎的出口氣體條件，再設計一具二氧化碳重組系統，並配合渦輪機出口氣體成份中氧氣含量過多的因素，進行兩組不同的實驗，一組探討是否能在甲烷量低於氧氣量的情況下找到一個最適當的溫度點，能讓甲烷與二氧化碳產生重組反應而不與氧氣燃燒，達到二氧化碳重組的目的；第二組則是添加大量的甲烷，希望在甲烷與氧氣燃燒過後，剩餘的甲烷能與二氧化碳產生重組反應，達到類似二氧化碳/甲烷部份氧化重組的效果，並探討在不同入口溫度、CH4/CO2值、觸媒個數、以及觸媒間距的情況下，二氧化碳重組的效果，與氫氣及一氧化碳的產量。
從目前結果來看，方案一不可行；方案二最佳二氧化碳轉化率出現在單段觸媒、CH4/CO2=7、T3=550 ℃的情況下，重組後剩下1.268莫耳的二氧化碳，轉化率達50%，氫氣產量12.210莫耳，一氧化碳產量3.493莫耳。從二氧化碳減量的觀點來看，本實驗結果並不如預期，目前還無法使重組後所剩餘的二氧化碳量低於重組前；從產氫的觀點，投入7莫耳的甲烷能得到12莫耳的氫氣，效果還算不錯。

The waste heat from gas turbine engine (about 500℃) is used as the heat resource to recycle carbon dioxide base on the concept of methane reforming. This study is the feasibility of recycled carbon dioxide from gas turbine engine exhausted gas by methane reforming. Our goal is to recycle waste heat and reduce carbon dioxide.
The exhaust gas from gas turbine was simulated by electrical heaters and flow meters, and a system of methane reforming was designed. Because the exhaust form gas turbine contains too much oxygen, the reforming and oxidation co-existed in these experiments. In the first experiment, it is tried to find a suitable temperature to allow the methane reformed only with carbon dioxide, instead of burning with oxygen. In the second experiment, a lot of methane was used and hope the surplus methane can react with carbon dioxide instead of reacting with oxygen, just like partial oxidation reaction. The effects of the efficiency of carbon reforming were also studied, and the yield of hydrogen and carbon monoxide in variable conditions, like variable temperature degrees, the ratio of CH4/CO2, numbers of catalysts, and distance of catalysts.
According to the results, the first experiment is not successful. The best result of the second experiment occurs in the condition of one set of catalyst, CH4/CO2=7, T3=550℃. After reforming, 1.268 mole of carbon dioxide is left, thus the conversion rate of carbon dioxide reaches 50%, and yield 12.210 mole of hydrogen and 3.493 mole of carbon monoxide. In terms of carbon dioxide reduction, this experiment is still not expected; the carbon dioxide quantity after the reforming wasn’t reduced. In terms of yield hydrogen, however, the result is acceptable: 7 mole of methane can generate 12 mole of hydrogen.
