| 摘 要： | 采用固相萃取技术将重馏分油分离为饱和烃和芳烃组分，并通过气相色谱-场电离飞行时间质谱联用仪（GC-FI TOF MS）分别进行分析。根据分子离子峰的精确相对分子质量可实现化合物的定性分析，根据分子离子峰强度进行定量分析，从而得到重馏分油饱和烃和芳烃的碳数分布信息。与现有的ASTM D 2786和D 3239烃类组成分析方法相比，本方法可提供更加详细的重馏分油烃类组成信息。

| Abstract: | Vacuum gas oil was separated into saturates and aromatics by solid phase extraction.The saturates and aromatics were then determined by gas chromatography-field ionization time of flight mass spectrometry(GC-FI TOF MS).The carbon number distribution of saturates and aromatics could be obtained by the accurate relative molecule mass and the relative abundance of their molecular ions.Compared with ASTM D 2786 and D 3239,more detailed information could be obtained by this method. |
