摘要
利用 1 0 0多种柴油样品对十六烷值的计算值与实测值进行比较 ,验证了GB/T 1 1 1 3 9- 89、ASTMD 976- 80及其修正式和ASTMD 976- 93公式的准确度。利用折射率反映烃类分子结构及分子量的物性 ,提出了由折射率预测柴油十六烷值的公式 ,该公式具有简单、快速、准确等优点 ,是计算柴油十六烷值的好方法。
The equations specified in GB/T11139-89, ASTM D976-80 and ASTM D976-93, which are used for prediction of the cetane number of diesel fuels, were verified through making a comparison between the calculated value and measured value of hundreds of diesel fuel samples. Moreover, a new equation for predicting the cetane number of diesel fuels from their refractive index was raised in this paper because the refractive index reflects the information about molecular structure and molecular weight of various hydrocarbon compounds. The experimental results show that the equation is a rapid, simple and accuracy method for the calculation of cetane number of diesel fuels.
