摘要

生質柴油不論料源為何，其生物降解速率遠快於傳統石化柴油，因此儲存環境勢必較石化柴油嚴謹。本研究針對生質柴油與不同摻配比例之生質柴油（如D100、B5、B20、B100），在不同儲存環境下，如水分含量、溫度、以及空氣接觸與否，分析其酸價、總生菌數、pH值等項目，以瞭解儲存過程中，環境因子對生質柴油降解的影響。結果顯示，初步認為對B100而言，溫度為最重要影響因子，水分會促進其酸敗速度；對B5及B20而言，水分對其酸價的貢獻，似乎大於溫度。

Biodiesel is the mono-alkyl esters of fatty acids produced from renewable resources such as refined vegetable oil, animal fats and used cooking oil. One of the main criteria for the quality of biodiesel is the storage stability. This study aimed to investigate the effect of environmental factors on the storage stability of biodiesel (B100) and biodiesel blends (B5 and B20). Experimental results demonstrated that biodiesel and biodiesel blends stored at 43℃, the acid number increased greatly after 16 weeks. Water content in B5, B20 and B100 will accelerate biodegradation due to hydrolysis. The results show that temperature is the important factor affecting the biodegradation of B100. Compared to the B100 data on the same condition, it appears that B5 and B20 may have a longer storage duration than B100. The biodegradation of biodiesel and biodiesel blends with time under different storage conditions is proved in this paper and hopefully useful to the industry, official and academic organizations.
