化石能源逐年枯竭，許多先進國家利用廢棄物資源再生方式產生替代性能源；而再生化石油品中含有之有機硫化合物於燃燒過程容易產生SO2的排放，形成對環境的汙染及人體之危害。因此，本研究針對現行離子溶液萃取及氧化脫硫系統之缺點，製備不同離子液體及使用臭氧取代雙氧水活化有機酸，進行目標有機硫化物之氧化及萃取，並應用於廢潤滑油及廢輪胎熱裂解油之操作最佳化試驗。 本計畫預計以三年為期程，階段性計劃分別為：（1）建立此萃取氧化系統對於指標有機硫之最佳化操作參數，並確立其反應機制及理論模式；（2）建立此以離子溶液萃取結合氧化脫硫系統針對高硫油品之最佳操作條件，並驗證離子液體、反萃取劑之再生以及?回收之效益；（3）建立一組12公升/小時處理量之再生化石油品萃取氧化脫硫處理模組，完成脫硫反應槽之設計與建置，驗證脫硫後油品之主要成分，並依據法規規定分析油品品質及其作為燃料油之可行性；最後，利用經濟效益模式，分析連此續流式萃取氧化脫硫模組實廠運行之經濟利益及對環境之影響。 In response to the resulting exhaustion of fossil fuel energy, many countries around the world are devoting their efforts in investigating waste energy recovery and reuse technology, including oil recovery from the pyrolysis process of waste tires. Therefore, this study focus on the drawback of current ionic liquid extraction (ILE) and oxidative desulfurization (OD) processes to develop different compositions of ionic solutions and utilize the ozone as the activation agent in replacing hydrogen peroxide, which applied to sulfur reduction from wasted lubricant oil and the pyrolysis oil recovered from waste tires. Moreover, their efficiency of ILE-OD technology is also examined. This project is based on the ideal of fossil fuel oil recycle and reuse as new energy, which is based on different research objects in three years. In the first year, the aim of the research focuses on the optimization of various conditions for organic sulfur compounds removal under ionic liquid extraction, and confirms its reaction mechanism and conceptual model. In the second year, the research aims on the optimization of various conditions for organic sulfur compounds removal under oxidative desulfurization combined with ionic liquid extraction. In the third year, different recovered oils are executed under the optimal desulfurization conditions by the ILE-OD technology in batch scale, where the best desulfurization efficiency for pyrolysis oil is carefully examined. Moreover, the continue ILE-OD system is designed under the treatment capacity of 12L/hour, where the optimal desulfurization conditions are also examined. Furthermore, a cost-benefit analysis (CBA) is used to directly measure the overall relationship between the benefits and the costs, and the distribution of those benefits and costs that is commonly implemented in units of money. This study is also a comprehensive economic analysis to support decision-making system. Finally, this project will achieve the goal of recovered oil reuse under oxidative desulfurization system combined with ionic liquid extraction to ensure the sustainable development of energy resource.
