摘要

为减少对传统植物油和动物脂肪的依赖,生物柴油生产的油料多样化是非常必要的。因此,采用响应面方法(RSM)对传统和超声波辅助单步酯交换工艺进行了优化,以利用新型原料蟒蛇脂肪油(PFO)生产生物柴油。采用传统方法(CM)和超声辅助方法(USM)的二阶多项式模型预测生物柴油产量,发现决定系数(R2)分别为 0.9946 和 0.9873。在以下反应条件下,根据模型计算得出的 USM 最佳生物柴油产率为 99.12%:PFO/ 甲醇比率为 33.77 wt%,PFO/KOH 比率为 1.05 wt%,反应时间为 128.53 分钟。最佳条件下的生物柴油产量结果表明,回归模型与实验数据一致。此外,USM 的生物柴油收率(98.90%)明显高于 CM 的生物柴油收率(92.73%)。特别是,在最佳条件下生产的 PFO 生物柴油的特性符合 EN 14,214 标准规范。总之,利用 USM 从 PFO 新原料中一步法生产生物柴油,可促进和采用更可持续、更环保的能源方法。

Optimization of ultrasound-assisted biodiesel production from python fat oil using response surface methodology
Diversification of oil feedstocks for biodiesel production is very necessary to reduce dependence on traditional vegetable oils and animal fats. Therefore, a conventional and ultrasound-assisted single-step transesterification process was optimized using response surface methodology (RSM) for biodiesel production from a novel feedstock python fat oil (PFO). Second-order polynomial models of the conventional (CM) and ultrasound-assisted (USM) methods were used to predict the biodiesel yield, and the coefficient of determination (R2) was found to be at 0.9946, and 0.9873, respectively. The optimal biodiesel yield of USM calculated from the model is 99.12 % with the following reaction conditions: PFO/methanol ratio of 33.77 wt%, PFO/KOH ratio of 1.05 wt%, and reaction time of 128.53 min. Biodiesel yield results under optimal conditions have demonstrated that the regression models are consistent with experimental data. Besides, the biodiesel yield of USM (98.90 %) was significantly higher than that of CM (92.73 %). In particular, the properties of PFO biodiesel produced under optimal conditions were found to agree with EN 14,214 standard specifications. In summary, single-step biodiesel production from the PFO new feedstock with USM can be commendably used to engender and adopt a more sustainable and environmentally friendly energy approach.
