| 摘要: | 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，本研究以「循環經濟」之概念，回收淨水廠之含鐵汙泥製備六價鐵氧化劑和鐵錳磁性顆粒吸附劑，將其應用於快速攪拌輔助氧化脫硫試驗，針對每一反應模式建立其最佳化之操作條件及確認主要之反應機制；並將此實驗結果應用於再生油品，建?實驗室模場試驗模組，提供?多最佳化之操作數據，以?日後實場建置之設計與操作控制。
本計畫預計以三年為期程，階段性計劃分別為：（1）建立以淨水廠汙泥製備的六價鐵氧化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）建立此以淨水廠汙泥製備的鐵錳磁性顆粒吸附劑結合氧化脫硫系統針對氧化後有機硫（?）吸附之最佳操作條件，並驗證六價鐵催化劑、磁性顆粒吸附劑之再生及其回收之效益；（3）建立一組60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 focusses on the concept of recycle economic, the ferrate and iron manganese magnetite, made by sludge recovered from drinking water treatment plant, applied to current high-speed mixing assisted oxidative desulfurization (HSM-OD) processes to exam the optimization of their operation conditions and compute its conceptual models, which applied to the sulfur reduction of wasted lubricant oil and the pyrolysis oil recovered from waste tires. Moreover, the efficiency of continuous HSM-OD module unit is also examined for the future setup of industrial application.
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 oxidation under the ferrate made by sludge recovered from drinking water treatment plant, and confirms its reaction mechanism and conceptual model. in the second year, the research aims on the optimization of various conditions for the adsorption of oxidized organic sulfur compounds using iron manganese magnetite made by sludge recovered from drinking water treatment plant. In the third year, different recovered oils are executed under the optimal desulfurization conditions by the HSM -OD technology in batch scale, where the best desulfurization efficiency for pyrolysis oil is carefully examined. Moreover, the continue HSM -OD system is designed under the treatment capacity of 60L/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 pyrolysis oil reuse under high-speed mixing oxidative system combined with solid adsorption to ensure the sustainable development of energy resource. |
