盐地碱蓬油制备生物柴油工艺条件研究

Optimization of technological process for synthesizing biodiesel from Suaeda salsa

以盐地碱蓬油为原料制备生物柴油。通过正交实验研究了反应温度、催化剂用量、醇油摩尔比、反应时间、搅拌强度等因素对生物柴油产率的影响。结果表明,在实验范围内各影响因素对生物柴油产率作用的大小依次为:搅拌强度>反应时间>催化剂用量>醇油摩尔比>反应温度。盐地碱蓬油制备生物柴油的最佳工艺参数为:搅拌强度为1 800 r/min,反应时间60min,催化剂KOH用量为盐地碱蓬油质量的1%,醇油摩尔比6/1,反应温度65℃,在该工艺条件下,生物柴油产率达到97.03%。

Suaeda salsa oil as raw materials was used to produce biodiesel.The orthogonal experiment combination design were adopted to study the effects of catalyst dosage,mole ratio of methanol to Suaeda salsaoil,reaction time and the rate of rotation on biodiesel production rate.The results indicated the order of factors that influence the biodiesel production rate within the experimental range was as follows:the rate of rotationr>reaction time>catalyst dosage>mole ratio of methanol to Suaeda salsa oil>...
