93~#、97~#汽油性能分析与鉴定

An Analysis and Identification of Gasoline No.93 and No.97

以93#、97#汽油为原料,通过油品的相关检测仪器,分别对两种车用汽油的相关物理化学性质进行了分析和鉴定。通过实验分析得出:93#汽油的性质与97#汽油的性质有很大的差别。93#汽油含有的烷烃等饱和烃比较多。它的密度小、颜色较浅、易于冷启动,其性质也相对稳定,而97#汽油里面含有的芳香烃、环烷烃等重质馏分比较多,它的密度较大、色度较深、平均蒸发性比较好,但不易冷启动,稳定性差。

This study, taking Gasoline No. 93 and No. 97 as its raw materials, analyzes and identifies their physical and chemical properties with oil detecting instruments. The experimental results show that there are some differences between the properties of the two： No. 93 contains more saturated hydrocar- bons like alkanes and as a result,it is more stable in its nature with lower density,lighter color, and easier to achieve a cold-start. While No. 97 contains more heavy distillates such as aromatic hydrocarbon and cycloalkane which makes it better in the average evaporation with higher density and darker color but hard to get a cold start and poor in stability.
