【摘要】：文章對(duì)棕櫚油生物柴油的低溫流動(dòng)性和氧化穩(wěn)定性進(jìn)行了分析,發(fā)現(xiàn)棕櫚油生物柴油具有較好的氧化穩(wěn)定性,但是低溫流動(dòng)性較差。通過(guò)不同的方法(與-10#柴油、油酸甲酯、菜籽油生物柴油按照不同體積比混合)對(duì)棕櫚油生物柴油的低溫流動(dòng)性進(jìn)行了改進(jìn),并利用流變儀和Rancimat法分析了改進(jìn)方法對(duì)棕櫚油生物柴油低溫流動(dòng)性及氧化穩(wěn)定性的影響。研究結(jié)果表明:與油酸甲酯混合可以降低棕櫚油生物柴油的膠凝點(diǎn),但其氧化穩(wěn)定性隨之變差;當(dāng)棕櫚油生物柴油的體積含量為5%~20%時(shí),與-10#柴油的混合使得油樣的膠凝點(diǎn)低于-10℃,氧化誘導(dǎo)期大于20 h;當(dāng)棕櫚油生物柴油的體積含量低于40%時(shí),與菜籽油生物柴油的混合使得油樣的膠凝點(diǎn)低于0℃,氧化誘導(dǎo)期大于6 h。
[Abstract]:The low temperature fluidity and oxidation stability of palm oil biodiesel were analyzed. It was found that palm oil biodiesel had good oxidation stability, but poor low temperature fluidity. The low temperature fluidity of palm oil biodiesel was improved by mixing rapeseed oil biodiesel with different volume ratio. The effects of the improved method on the low temperature fluidity and oxidation stability of palm oil biodiesel were analyzed by means of rheometer and Rancimat. The results showed that mixing with methyl oleate could reduce the gel condensation point of palm oil biodiesel. When the volume content of palm oil biodiesel is 5 ~ 20, the gel condensation point of the oil sample is lower than -10 鈩，
