摘要
建立了 GC/MS 测定 VGO 馏分烃类组成沸点分布的新方法。该方法采用固相萃取技术分离出饱和烃和芳烃馏分,然后用双柱分流的方式,同时进入质谱和 FID 检测器,得到样品的色谱图和总离子流色谱图。通过自行编制的数据处理程序,得到 VGO 样品烃类组成沸点分布,所得结果与标准方法测定结果接近,该方法具有很好的准确性。
A new method was established for the determination of boiling point distributions of various hydrocarbon types in vacuum gas oil（VGO）. The VGO sample was separated into saturates and aromatics by solid phase extraction,and then the separated samples were divided into MSD and FID for measurement simultaneously using GC/MS unit with a double-column device. The boiling point distributions of various hydrocarbons in VGO were calculated from the FID and TIC chromatograms by a home-developed data processing program. The obtained results agreed well with the test results of standard method.
