摘要
原油供应劣质化和产品要求清洁化的矛盾日益突出,为了优化炼化生产过程而提出了“分子炼油”的概念,即从分子组成与转化层面深入地了解并干预炼化过程。质谱技术是实现重油分子组成表征最强有力的工具,近年来傅里叶变换离子回旋共振质谱仪的发展和应用为研究复杂重油体系的分子组成提供了技术基础。以质谱技术为切入点,综述了重油分子组成的表征方法,并对重油分子组成表征的发展前景进行展望。
The contradiction between the poor supply of crude oil and the cleanness requirement of product has become increasingly prominent.In order to optimize the refining process,the concept of molecular refining was proposed,which need to understand and interfere the refining process from the perspective of molecular composition and transformation.Mass spectrometry is the most powerful tool to realize the molecular composition characterization of heavy oil.In recent years,the development and application of Fourier transform ion cyclotron resonance mass spectrometer has provided a technical basis for studying the molecular composition of heavy oil system.Taking mass spectrometry techniques as an entry point,molecular composition characterization methods of heavy oil are reviewed,and the development prospects of heavy oil molecular composition characterization are prospected.
