摘要

为了确保更有效的脂质提取方法，本研究研究研究了一种新型的激光吸收剂提取脂质的方法，并寻求其最佳操作控制。此外，本研究还比较了最佳条件下激光提取法和现有提取法的脂质提取效率和FAME转化率。优化激光提取脂质的实验结果表明，当激光输出功率为75Wh/L时，提取效率最高（81.8%）。采用微波处理作为预处理工艺，萃取效率提高了90.8%。在激光提取脂质的过程中，添加吸收剂比激光和化学法具有更高的提取效率。研究还发现，吸收剂激光提取法提取的脂质中总脂肪酸含量（853.7mg/g油）高于化学提取法（825.4mg/g油。此外，它的FAME转化率最高（94.2%）。

Enhanced lipid extraction from microalgae in biodiesel production

In order to secure more effective lipid extraction method, this research investigated new lipid extraction method using laser with absorbent and sought its optimum operation control. In addition, this study compared lipid extraction efficiency and FAME conversion rate between laser extraction method at optimum condition and existing extraction method. Results from experiments for optimizing lipid extraction method using laser showed that the maximum extraction efficiency (81.8%) was attained when using laser with an output capacity of 75Wh/L. Extraction efficiency increased up to 90.8% when microwave treatment as pretreatment process was conducted. Addition of absorbents during lipid extraction process with laser showed higher extraction efficiency than laser and chemical method. It was also found that laser extraction method with absorbent had higher total fatty acid content (853.7 mg/g oil) in extracted lipid than chemical extraction method (825.4 mg/g oil). Furthermore, it had the highest FAME conversion rate (94.2%).
