摘要:	台灣目前有許多廢油處理廠面臨再生之油品含高濃度之有機硫，不符合燃油之環保法規之規定，無法進行燃油直接利用。而各國現行之主要脫硫法為加氫脫硫法，其建置及維護成本甚高，若能研發一經濟且安全之油品脫硫技術，將可改善業者建廠成本過高問題，並提升回收油品之品質。本實驗使用離子液體(1-丁基-3-甲基咪唑四氟硼化鹽)作為萃取液，透過氧化萃取脫硫法，來去除廢油品中的硫份，在研究中使用雙氧水(氧化劑)、鎢磷酸(過度金屬催化劑)、溴化四辛基銨(界面活性劑)作為氧化藥品，氧化實驗結果的最佳參數為雙氧水(濃度50％)70毫升、鎢磷酸0.75公克、溴化四辛基銨3公克及氧化時間30分鐘，其氧化硫份去除率為29.61％，而萃取實驗結果的最佳參數為離子液體50毫升、轉速6000rpm、時間40分鐘，其萃取硫份去除率為25.9％。根據本研究之結果，氧化萃取脫硫法確實能有效的去除廢油品中的硫分，但還是具有很大的進步空間，來優化對廢油品中含硫量的去除效果。 At present, there are many waste oil treatment plants in Taiwan that face reclaimed oil products containing high concentrations of organic sulfur, which are not in compliance with the fuel environmental regulations and cannot directly use fuel. However, the current major desulfurization method for hydrodesulfurization in various countries has a high cost of construction and maintenance. If an economical and safe oil desulfurization technology can be developed, it will improve the cost of setting up factories. Improve the quality of recycled oil products. In this experiment, an ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate) was used as an extract, and the sulfur content of the waste oil was removed by an oxidative extraction desulfurization method. Hydrogen peroxide (oxidant) was used in the study. Tungstophosphoric acid (excess metal catalyst), tetraoctyl ammonium bromide (surfactant) as an oxidizing agent, the best parameters of oxidation experiment results are 70 ml of hydrogen peroxide, 0.75 g of tungsten phosphate, 3 g of tetraoctyl ammonium bromide and oxidation. At 30 minutes, the sulfur oxide removal rate was 29.61%, and the optimal parameters of the extraction experiment were 50 ml of ionic liquid, 6000 rpm, and 40 minutes, and the sulfur removal rate was 25.9%. According to the results of this study, the oxidative extraction desulfurization method can effectively remove the sulfur in the waste oil, but there is still much room for improvement to optimize the removal of sulfur in the waste oil.
