摘要
采用国产高分辨毛细管气相色谱对汽油组成进行分离。按照各组分或者相关的组分组对汽油辛烷值的贡献, 将选定色谱条件下的汽油组分简化分为三组,对每组的总峰面积及与之相适应的三个相关系数进行回归及加合,以求得汽油的测定辛烷值。在不同标号的汽油测定实验中,测定辛烷值的绝对误差小于等于0. 5个辛烷值单位,分析准确度满足要求。
Components from gasoline samples were analyzed by high resolution capillary column and gas chromatography. Components from gasoline samples were divided into 3 groups, which were then defined as variable according to their contribution to the actually determined octane number. Linear regression used for the calculation of octane number was established on the basis of variables, and parameters of each group were determined. Result deviations were about 0.5 units and satisfy for the requirement of ordinary determination of octane number.
