摘要
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。
GS, a FCC gasoline sample, was first distilled into 6 cuts, and the detailed sulfur compositions present in each cut were analyzed using an Agilent 6890 gas chromatograph configured with an G2350A atomic emission detector (GC/AED) The data show that the sulfur compounds are mainly thiophenes and alkylsubstituted thiophenes, and the distribution of sulfur is not uniform, and a large part is concentrated in the heavy cut of the sample The data can also be used to estimate the cut point between light and heavy cuts, which is helpful to remove sulfur effectively by different methods at lowest cost
