本研究採用水熱碳化法轉製廢輪胎為活性碳，用在汞蒸氣吸附去除。與傳統乾式裂解碳化製程不同的是，水熱碳化可以保留廢棄輪胎中的硫元素並且同時添加活化劑以減少製程時間與藥劑用量。我們調控水熱碳化變因(如溫度、時間、水量與ZnCl2)以及活化變因(溫度與活化劑)建構其與元素汞吸附量的關連性。製得材料以場發射掃描式電子顯微鏡(FESEM)、熱重/熱流分析儀(TGA/DSC)、元素分析(EA)、X-射線光電子能譜儀(XPS)以及氮氣等溫吸脫附實驗分析其特性與成分。第一年期的主要研究成果有:( 1)確認量大、價廉的廢棄轎車胎效果較廢棄卡車胎好。(2)水熱碳化法可轉化廢棄輪胎為固態碳，獲得活性碳的產率達~50%。(3)整合碳化與活化程序並確認活化劑到達材料內部。其表面積達435 m2/g。(4)水熱碳化法可增加表面含氧官能基且保留廢棄輪胎中固有的2 wt%硫元素以增強汞蒸氣的吸附。(5) 30分鐘的元素汞吸附實驗，本研究製得的活性碳對汞元素的吸附能力約為商業活性碳的90%，但價格為商業活性碳的1/2。接續的工作在於增加汞元素吸附能力、降低製作成本以及模擬燃煤發電廠含汞污染尾氣去除的最佳操作條件及經濟效益評估，並探討吸附之界面化學及反應機制，以利提升吸附汞的效果，達到廢棄物能源永續利用的目的。

This project joint to prepare and to characterize activated carbon hydrothermally converted from scrap tire as well as to apply to Hg(0) adsorption. We will introduce the production of activated carbon starting from scrap tire using a facile, scalable hydrothermal carbonization process. In order to rationally design a process in which an activated carbon fabricated by hydrothermal process is involved, it is necessary to study different aspects: the synthesis of the material, its characterization, and also the design of the process (reactor, operating conditions, etc.). The characterization such as XANES, FTIR, TPD-MASS and XPS will be carried out. The results of the 1st-year project include (1) to make sure the advantage of scrap car tire over scarp truck tire, (2) the yield above 50%, (3) the specific surface are above 435 m2/g, (4) 2wt% sulfur on the obtained activated carbon with various oxygen-containing functional, (5) 90% of Hg(0) adsorption capacity of commercial activated carbons with 1/2 cost. Further work will focus on the improvement of Hg(0) adsorption using modifying the preparation conditions and with lower cost.
