Abstract:

The effect of water content and storage material on the moisture and the acid number of 5% biodiesel from cotton seed oil，rubber tree seed oil and Jatropha curcas L. seed oil with 0^# diesel blends was studied. The results showed that moisture and acid number of the B5 blends did not significantly change and could meet the national quality standards with addition of less than 1.0% water after 70 days storage at room temperature. B5 biodiesel-diesel blends can be stored in glass，plastic and steel containers.

摘要：

研究了水分和储存材质对棉籽油生物柴油、橡胶籽油生物柴油和小桐子油生物柴油与0^#柴油混配物B5水分含量和酸值的影响。结果表明，上述3种B5生物柴油混配物在常温避光密封存放70天后，水分含量和酸值均满足国家标准；对比添加水分（≤1.0%）样品的酸值和水分含量发现，样品性质无显著变化。生物柴油和石化柴油混配物B5可采用玻璃、塑料、碳钢材质储存。
