摘要
高效利用石油资源和生产高质量石油产品要求从分子水平认识石油化学组成,而饱和烃作为石油中最主要的一类组分,其分子组成分析是石油化学研究的重要课题。总结了石油饱和烃的分子组成分析方法并简要介绍其应用,主要包括基于气相色谱技术的单体烃分析方法和基于质谱技术的分子/族组成分析方法。针对石油饱和烃的质谱电离技术,总结了各方法的技术优势及存在的问题,对相关技术和方法的发展前景给予展望。
Knowledge of petroleum composition at the molecular level is critical to efficient utilization of petroleum resources and producing high-quality products. The importance of molecular characterization of saturated hydrocarbons, which is the major and high-value components of petroleum, is clear. In this article, analytical methods for molecular characterization of saturated hydrocarbons in petroleum and the applications of these methods were introduced. Individual saturated hydrocarbons analysis based on gas chromatography and saturated hydrocarbons types analysis and molecular composition analysis based on mass spectrometry(MS) were the major analytical methods. Various ionization techniques of saturated hydrocarbons in MS analysis were introduced emphatically, the advantages and defects of these techniques were summarized. Finally, the development prospect of related techniques and methods were prospected.
