棒状薄层色谱法测定渣油加氢尾油族组成的应用

Application of Rod Thin Layer Chromatography in Determination of Group Components of Residue Hydrogenation Tail Oil

棒状薄层色谱法测定重油四组分具有快速、微量、环境友好、重复性好等特点。文章采用薄层色谱法SY/T 5119—2016《岩石中可溶有机物及原油族组分分析》对测定渣油加氢尾油的应用做了研究,棒状薄层色谱法可用于尾油分析,且具有重复性高、操作步骤简单、用量少的特点。同时,文章对影响棒状薄层色谱测定结果的稀释、点样、展开、溶剂、环境等影响因素进行了分析,并提出解决对策。

The method for the determination of group components of heavy oil by Rod thin layer chromatography is fast, trace,environmentally friendly and reproducible. In this paper, the application of thin layer chromatography SY/T 5119—2016 "Ananlysis method for family composition of rock extracts and crude oil" to determine hydrogenation tail oil was studied.Rod thin layer chromatography can be used for tail oil analysis, and has the characteristics of high repeatability, less operation steps and simple amount. At the same times, the influencing factors such as dilution, sampling, expansion, solvent and environment on rod thin layer chromatography determination results were analyzed and the countermeasures are proposed.
