技術說明

本發明之廢棄水泥為觸媒以生產再生能源-生質柴油，可有效降低生質柴油生產成本與水泥廢棄物的資源回收。其方法包括： 製備觸媒：取廢棄水泥進行研磨後在鍛燒，溫度介於攝氏 150 至 900 度下得到固態觸媒； 轉酯化反應：取三酸甘油脂及醇類加熱冷凝回流，並添加上述固態觸媒進行轉酯化反應，製得生質柴油(脂肪酸甲酯)及甘油； 產物純化：將脂肪酸甲酯、甘油及固態觸媒以離心機分離，並以去離子水洗淨數次後，加熱抽氣以去除樣品中的甲醇; 觸媒分析：以X光粉末繞射儀、掃瞄電子顯微鏡-元素分析儀、熱重-熱差分析儀分析觸媒。 藉此，提升轉酯化反應之轉酯率，俾符合工業上大量製造之需求。 This study represented its originality in utilization of the waste cement as a solid catalyst for the renewable energy (biodiesel) production. Application of waste cement as catalyst for biodiesel production in this study not only provides a cost-effective and environment friendly way of recycling cement waste but also hopefully reduce the cost of biodiesel production. The biodiesel production of cement catalyst are as following: Catalyst Prepared: Calcination was performed in a muffled furnace at various temperatures between 150-950 °C for 3 hrs under static air after crushing the waste cement block. Transesterification reaction: The reactor was initially filled with the mixture of triglyceride, methanol and the catalyst, which was heated by a hot equipment with a condenser system. The catalysts were characterized by X-ray diffraction (XRD), TG differential thermal analysis (TGA-DTA), scanning electron-microscopy (SEM) and energy dispersive spectroscopy (EDS).
