摘要

本文探討生質柴油、柴油與乙醇(10% & 20%)及丙醇(10% & 20%)混合後的燃燒現象，將生質柴油、柴油加入了醇類於21毫升的燃燒室內燃燒後，使用氣相層析儀分析所排放CO2的體積百萬分率(ppmv)並計算礦化百分率，觀察液滴的大小和醇類濃度與汙染物的關係，和液滴狀態下何種油料最接近完全燃燒。
從實驗的結果顯示發現，生質柴油加入25%以上的醇類會有微爆的可能，因此生質柴油只加入20%以下的乙醇並發現礦化百分率及CO2的體積百萬分率不會有明顯的改變，但加入20%正丙醇在礦化百分率上則有提高的趨勢。另外本實驗亦考慮柴油在與生質柴油、乙醇混合燃燒以後，從氣相層析儀上測得礦化百分率與CO2排放比燃燒純柴油有明顯增加的趨勢。

The aim of this study of droplet pollution is to investigate combustion of blended fuels with alcohol(ethanol 10% &20% and propanol 10%&20%) and biodiesel/diesel. We use gas chromatography to measure the CO2 parts per million by volume and use this result to obtain the percentage of remineralization in a 21ml tank. We explore the relationship between the size of droplet, the concentration of alcohol, and the concentration of pollution. And, we also discuss which blended fuel is closer to complete combustion.
We find that biodiesel is added over 25% alcohol causes micro-explosion. The results of gas chromatography show that the percentage of remineralization and CO2 parts per million by volume are not changed if the combustion of biodiesel is added with ethanol less than 20%. But the percentage of remineralization is higher when combustion of biodiesel is added with 20% propanol . The combustion of diesel with alcohol and biodiesel leads to higher percentage of remineralization and higher CO2 parts per million by volume than the combustion of only diesel.
