液化石油气罐底油中有机硫化物组成分析

Characterization and Identification of Organic Sulfide Compounds in the Heavy Oil of Liquefied Petroleum Gas

摘要: 通过改进的硅胶/氯化钯柱配位色谱法分离出家用液化石油气罐底油中的硫化物，利用气相色谱-脉冲火焰光度检测器(GC/PFPD)和气相色谱-质谱(GC/MS)联用法对硫化物进行组成分析。结果表明,液化石油气罐底油中主要的含硫化合物为链状的硫醚，分子中含有1~3个硫原子，化合物碳数分布在 C₂~C₈之间，未发现噻吩类化合物。

Abstract: Sulfur compounds in the heavy oil of liquefied petroleum gas (LPG) were separated by silic gel/PbCl₂ column chromatograph， and analyzed by gas chromatograph-pulse flame photometric detector (GC/PFPD) and gas chromatography-mass spectrometry (GC/MS). The result shows that the sulfides are the major sulphur compound in the heavy oil. The number of sulphur atom is 1-3， and carbon number of the sulphur is 2-8. Thiophenic compounds are not ideatified.
