FCC汽油样品GS按沸点切割成六个组分,然后使用配有原子发射光谱检测器的气相色谱仪(GC AED)分别分析每个馏分样品中的含硫化合物。数据表明,样品中含硫化合物以噻吩和烷基取代噻吩类为主,而且含硫化合物在样品中的分布是不均匀的,随着切割段沸点的提高,含硫化合物含量明显增加,多碳数取代噻吩类化合物含量增加。数据还可以用来参考确定轻、重馏分油切割点,以对轻、重馏分油采取不同的脱硫方法,达到最佳经济效益。 The FCC gasoline sample, GS, was cut into six components by boiling point and the sulfur compounds in each of the fraction samples were analyzed separately using a gas chromatograph (GC AED) equipped with an atomic emission spectrometry detector. The data show that the thiophene-containing compounds are mainly thiophene-substituted thiophenes and the sulfur-containing compounds are not uniformly distributed in the sample. With the increase of the boiling point of the cutting section, the content of sulfur-containing compounds is obviously increased. The number of substituted thiophenes increased. The data can also be used for reference to determine the light and heavy distillate cut points, in order to light and heavy distillate to take different desulfurization methods, to achieve the best value for money.
