摘要

考慮到石化燃料的蘊藏量有限，又CO2排放量的快速增加造成嚴重的溫室效應，使得地球生態及大氣環境正迅速的惡化中。面對這重要的課題，舉世漠不關心，正視此問題的解決對策，首先，能減緩石化燃料的消耗又不增加CO2排放量最可行的能源即是生質燃料，其中玉米除了可供製生質酒精外又可製成生質柴油，且玉米油的含油率又是大豆油的兩倍，是可利用成為生質柴油的原料。故本研究使用甲酯化反應的玉米油甲酯生質柴油，經內燃機實驗後所得結果得知，使用玉米油甲酯生質柴油為燃料時，在不影響引擎性能的情形下，其燃料消耗率及NOX排放濃度比石化高級柴油分別高約11.99％和11.06％，而Smoke和HC的排放濃度分別低約52.47％和16.51％。因此，以玉米為原料轉製生質柴油亦是發展生質燃料的新選擇。

The global atmospheric concentration of CO2 emission is increasing very quickly so that it has made greenhouse effect very serious as well as to consider all the resource of the fossil fuel in the earth is limited. Human being is facing a very important lesson that the earth ecology and atmosphere environments are deteriorating very fast, but all over the world haven’t paid their attention still. The strategy for solving this problem is to decrease fossil fuel consumption as well as the amount of CO2 emission is decreased as well. So the most possible way is biodiesel used at first. Especially the corns, it can be a material of biodiesel. Because it provides not only the material of biodiesel but also bioethanol and the rate of oil retaining for corn oil is double than soybean oil. So the corn oil methyl ester biodiesel used in this study that is made from transesterification reaction. After diesel engine experiment, experimental results demonstrated that using corn oil methyl ester biodiesel, which is based on no influence of engine performance has higher BSFC and the concentration of than premium diesel about 11.99% and 11.06%, respectively. Moreover, its emission concentration of Smoke and HC are lower than premium diesel about 52.47% and 16.51%, respectively. Therefore, the corn is a new choice of material to develop biofuel by transesterifying into biodiesel.
