本研究之目的是將二氧化碳在化工廠內捕獲並高壓液化封存，並產生乾淨的氫氣與電力提供給大眾社會使用，以減少二氧化碳排放，因此使用鈣循環與化學迴路系統做為本研究捕碳產氫的製程。
本研究以快速流體化床與逆流式移動床為基礎，透過Matlab建立鈣循環與化學迴路反應器之數學模型，並分析最適化其模擬結果。且以J. C. Abanades以及L. S. Fan的文獻加以驗證。
模擬結果顯示，鈣循環透過氧化鈣在快速流體化床內循環操作，能捕獲工廠尾氣超過70%的二氧化碳，也能在合成氣的進料中生產將近兩倍的氫氣；而化學迴路能以載氧體氧化還原的方式捕獲二氧化碳並生產純度接近100%的氫氣。
本研究亦結合Matlab的模型與Aspen plus®的流程模擬，模擬鈣循環與化學迴路個別應用在沃巴什河煤氣化電廠內的狀況。其結果顯示此二種製程皆能捕獲二氧化碳，並生產氫氣。而化學迴路在電廠內能有較高的熱效率或氫氣品質；鈣循環有較高的操作彈性與負荷，就能使用在高產量的工廠內。各工廠能參考本研究之模擬結果，根據實際的操作狀況，選擇適合的系統應用在工廠內。

In order to lower down the CO2 emission without reducing the energy suppling, CO2 Capture and Storage in the plant, clean energy production such as Hydrogen and electricity are the main focus and principle of this study. As a result, Calcium and Chemical Looping systems are introduced in this study.

This study is based on the Fast Fluidized Bed and Countercurrent Moving Bed mathematical models built by Matlab. The simulation, analysis and optimization of Calcium and Chemical Looping are also being discussed. These models are also validated by J. C. Abanades and L. S. Fan’s previous work.

The results show that Calcium Looping could circulate CaO particles in two fast fluidized bed to capture more than 70% CO2 from tail gas and generate almost twice Hydrogen from Syngas inlet; Chemical Looping could use Oxygen carrier to fully oxide the Syngas and reduce H2O to produce almost 100% pure Hydrogen.

This study also used Aspen Plus® to simulate the application of these two systems in coal gasification power plant. The results show that Chemical Looping has higher purity Hydrogen production and heat efficiency, and Calcium Looping has more operating tolerance and capacity, which is suitable to be installed in large production plant. People could consider the operating condition and take this as reference to choose the most suitable system for their plants.
