中文摘要:
      选用棉籽油、煎炸废油和无患子油作为原料,通过酯交换反应制备三种不同生物柴油,采用气相色谱-质谱联用(GC-MS)技术分析了三种生物柴油的脂肪酸甲酯成分及其含量. 分析表明:三种生物柴油主要由棕榈酸甲酯、亚油酸甲酯、油酸甲酯和硬脂酸甲酯组成,无患子油生物柴油含有较多的花生一烯酸甲酯和花生酸甲酯. 研究共鉴定了13种脂肪酸甲酯,分析比较了三种生物柴油的所含甲酯的异同点,并提出了研究脂肪酸甲酯成分和含量对生物柴油理化性能指标影响的必要性.
英文摘要:
      Three kinds of feedstocks (the cottonseed oil,the waste oil and the soapberry oil) are selected in this research work to produce biodiesel with transesterification reaction. These three kinds of biodiesel are analyzed through gas chromatography-mass spectrometry (GC-MS) analysis method to get the detail fatty acid methyl ester composition and the corresponding contents. The analyzing results indicated that the methyl palmitate,the methyl linoleate,the methyl oleate and the methyl stearate are the main components of these three kinds of biodiesels,and the soapberry biodiesel has more methyl eicosenoate and methyl arachidate. Totally,13 kinds of fatty acid methyl ester have been identified in this research work. And the similarities and differences of the ester components among three kinds of biodiesels are analyzed.The analysis of composition and content of fatty acid methyl ester is found to be important in the study of biodiesel physicochemical properties.
