摘要

本研究係以固態觸媒轉酯化技術生產生質柴油。首先探討操作條件對轉酯化反應之影響，並以大豆油之料源進行測試，實驗結果顯示，提升反應溫度、壓力、醇油莫爾比與延長反應滯留時間，皆可提高生質柴油的產率。而填充觸媒之選擇以鹼性觸媒＞中性觸媒＞酸性觸媒，小粒徑觸媒優於大粒徑觸媒，觸媒添加量與觸媒填充量越多，則越有利於生質柴油生產；以鹼性觸媒為例，觸媒經100小時以上操作測試後仍可維持不錯的觸媒活性，觸媒經高溫再生程序後，也沒有明顯的失活現象發生。另外使用大豆油、蓖麻油與痲瘋樹籽油三種不同料源，與填充BG-BC-1觸媒時，在操作條件為1,300 psi、250℃、醇油莫爾比23:1與滯留時間11分鐘下，其生質柴油皆可高於95 %以上的產率。

A study on biodiesel produced by transesterification technology with solid catalyst and soybean oil as oil feedstock has been carried out in a pilot scale testing. The results showed that the higher temperature, pressure, methanol-oil molar ratio as well as the longer residence time, the higher production rate of biodiesel. The order of selection of packing catalysts is base catalyst ＞ neutral catalyst ＞ acid catalyst, catalysts with small particle size is better than that with big particle size. The increasing of the content of catalyst on Al2O3 support and of the weight of packing catalyst results in the higher production of biodiesel. As the example of base catalyst, the catalyst is keeping higher catalytic activity during the long-term operating test (more than 100 hours). The regenerated catalyst with high-temperature sintering process is not obviously deactive. Moreover, as using different oil feedstocks (such as soybean oil, jatropha oil, and castor oil) and packing BG-BC-1 catalyst, the productions of biodiesel for different oil feedstocks are higher than 95% under the operation conditions of 1,300psi, 250℃, methanol-oil molar ratio 23, and residence time 11 min.
