    Abstract: 本研究所用廢咖啡渣是從OKLAO 咖啡屋收集來的,並在 105 oC 的烤箱中過夜烘乾,
    以去除水分。咖啡油的萃取是採用索氏萃取方法及簡單的回流萃取系統。萃取中用 n-
    己烷和甲醇兩種低沸點有機溶劑來萃取。實驗中使用簡單蒸餾方法分離溶劑與咖啡油。
    實驗結果顯示,咖啡油在咖啡渣中的含量介於 10-15 %w / w (以乾重為計算基準) 之
    間。咖啡油在 65 oC 與無水甲醇經轉酯化反應2 h,並在催化劑氫氧化鈉 (NaOH) 或固
    體鹼MgO/ZrO2或酸化的活性炭的催化下,被製備成生質柴油。咖啡油的轉化率約 92%。
    此外,可以由皂化過程成把咖啡油製成咖啡肥皂。而廢咖啡渣經萃取咖啡油後的剩餘固
    體,也可以轉化為活性炭。
