十六烷值是评价生物柴油燃料质量的重要参数。其测定通常是艰巨且昂贵的，并且由于实验误差而获得的结果并不总是准确的。这项工作的目的是建立脂肪酸甲酯（FAME）组成与十六烷值（CN）之间的关系。数据收集自有关各种生物柴油燃料的十六烷值及其 FAME 组成的文献。对纯 FAME 进行回归分析，建立十六烷值和 FAME 组成之间的关系。建立了一个方程，将十六烷值与生物柴油燃料的 FAME 重量百分比组成相关联。预测的十六烷值与平均测量的十六烷值非常吻合。这项工作确定了十六烷值对生物柴油 FAME 组成的一般依赖性。
Cetane number is an important parameter in evaluating the quality of biodiesel fuel. Its determination is usually arduous and expensive, and the results obtained are not always accurate due to experimental error. This work is aimed at deve- loping a relationship between the fatty acid methyl ester (FAME) composition and the cetane number (CN). Data were collected from the literature on the cetane number of various biodiesel fuels and their FAME composition. A regres- sion analysis was performed on pure FAME to establish a rela- tionship between the cetane number and FAME composition. An equation was developed relating the cetane number with the % composition by weight of FAME of biodiesel fuel. The pre- dicted cetane number values compare well with the average measured cetane number values. This work establishes the general dependence of cetane number on FAME composition of biodiesels.
