TEPA与降凝剂复配对生物柴油离子含量的影响Effect of the combination of TEPA and pour point depressant on the ion content of biodiesel

open access: yesZhongguo youzhi, 2023
为对生物柴油的规模化应用提供参考,以小桐子生物柴油为研究对象,利用离子色谱系统研究了5种降凝剂(平安者、秒速、易威、凡响、海龙)、抗氧化剂四乙烯五胺(TEPA)及其复配物对生物柴油离子含量的影响,并测定了加入不同添加剂生物柴油的凝点及氧化安定性。结果表明:TEPA与降凝剂复配在一定程度上降低了生物柴油的凝点,延长了生物柴油的氧化诱导期,其中抗氧化效果最好的是TEPA与易威复配;5种降凝剂添加量为0.4%时,油样中不同种类的离子含量变化趋势不同,有机酸离子含量变化较小,无机阴离子和阳离子含量降低,其中NO-
