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

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。

Sulfur compounds in the heavy oil of liquefied petroleum gas （LPG） were separated by silic gel/PbC12 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.
