生物柴油质量分析检测的评价

Assessment of methods used in biodiesel

生物柴油可作为石化柴油的替代燃料,对其检测及质量的评定是一项非常重要的任务。目前,常用的方法包括色谱法和光谱法,对各类方法及其优缺点进行了论述。

Biodiesel, an alternative diesel fuel derived from vegetable oils, animal fats or waste vegetable oils,is obtained by transesterificafion with methanol in the presence of catalysts to give corresponding mono-alkyl esters. It is important to monitor the progress of the transesterification reaction or give an assessment of the quailty of the product. At present, there are two major categaries, which including chromatographic and spectroscopic methods. This article gives some comments on various methods in different categories, including advantages and disadvantages.
