摘要
重油的开发和利用日趋重要。只有对重油的结构和组成有充分的了解,才能合理地利用这部分有限的资源。核磁共振谱图能够直接反映出碳、氢及杂原子所处的化学环境,且分析简便、快捷,从而成为沥青、渣油等重油的结构组成分析的有力工具。本文概述了近年来核磁共振技术在重油结构和组成分析方面所做的主要研究。
The importance of heavy oils in petroleum processing is increasing. To utilize well the limited resources, it is necessary to know more of the infornlations of the structures and composition of heavy oils. Nuclear magnetic resonance（NMR） spectroscopy has emerged as a powerful analytical tool for the determination of heavy oils composition due to its rapidity, directness, and ease of analysis. In this paper, the main research work on the application of NMR to the analysis of the structures and composition of heavy oils conducted in recent years is reviewed with 48 references.
