摘要

國產千年桐、無患子、烏桕及樟樹分別測定果實組成分，油脂理化性質；並以種子油製造脂肪酸甲酯（生質柴油）及副產物（甘油），所得結果歸納如下：
1、烏桕及千年桐果實獲油率最高約為24.2-24.7%，樟樹者為22.6%，而無患子果實最低僅4%。
2、四種林木種子油皆能夠在適當條件完成轉酯化反應；千年桐、無患子及樟樹等種子油之酯含量高達於98%以上，而烏桕僅62.9%。基於種子油所得脂肪酸甲酯之種類、含量、冷濾點、碘價…等性質、轉酯化作業、成本觀點，綜合得知千年桐及無患子種子油較適合作為生質柴油原料。

The domestic seeds of wood oil tree, soapnut tree, Chinese tallow tree and camphor tree were examined in the following aspects: consist of fruits, quality of chemical and physical properties of oil, the seed-oil-production of fatty acid methyl ester (bio-diesel) and the by-products (glycerin). We found: (1) In terms of the yield of bio-diesel, the seeds of Chinese tallow tree and wood oil tree had the highest output (about 24.2-24.7%), the camphor tree was the middle one (about 22.6%), and soapnut tree had the lowest (about 4%). (2) All the four seeds can finish the transesterification improper conditions. The seeds of Wood oil tree, soapnut tree and camphor tree had above 98% therate of the transesterification, while Chinese tallow tree only had 62.9%. Besides, the kinds of bio-diesel from the different seeds differed in amounts, cold filter plugging point, iodine value, properties, transesterification process and cost. To sum up, according to this study, soapnut tree and wood oil tree are the optimal choices as bio-diesel raw materials.
