摘要
石油及其产品由大量复杂的有机物组成,油品族组成的详细分析对生产工艺的选择、产品的质量控制、环境保护及新油品的开发具有十分重要的意义.本文简述了石油及其产品组成分析的测定方法,介绍了核磁共振技术在油品组成分析中的特点及工作原理以及核磁共振技术在汽油族组成、柴油多环芳烃、航煤族组成、石脑油烃族组成(PONA)、汽油苯含量和其他理化性质分析中的应用情况.结果表明:核磁共振技术在油品组成的分析中具有分析速度快、分析项目多、结果准确可靠、适用性强、操作简单等优势.
Abstract
Petroleum and it's products are made up of large amounts of complex organic matter.A detailed analysis of the composition of the oil is of great significance for the selection of production processes,the quali-ty control of the products,environmental protection and the development of new oil products.The methods and instruments for determining the composition of petroleum and its products were described,and the characteris-tics and working principles of nuclear magnetic resonance technology in the analysis of oil composition were al-so introduced,and the application of nuclear magnetic resonance(NMR)technology in gasoline group compo-sition,diesel polycyclic aromatic hydrocarbons,aviation coal group composition,naphtha hydrocarbon group composition,and gasoline benzene content was also described.NMR has the advantages of rapid analysis,many analysis items,reliable results and strong applicability in oil composition concentration analysis.
