汽油烃组成分析的标准化方法评述

汽油的烃组成指标是车用汽油清洁化进程的重要项目。通过大量的比对试验分析了不同汽油烃组成测定方法的技术特点，介绍了中国石化石油化工科学研究院采用多维气相色谱快速测定汽油中烯烃、芳烃和苯含量的研究、实践以及标准化的历程，该方法的研究及标准化为炼化企业清洁汽油生产的质量升级和产品质量保障以及流通市场汽油质量的监控发挥了重要作用，并成为我国主导制定的石油及石油产品领域的第一个国际化标准。

REVIEW ON STANDARD TEST METHODS FOR DETERMINATION OF HYDROCARBON COMPOSITIONS OF GASOLINE

The contents of olefins, aromatics and benzene are the important quality specifications of gasoline. The determination of olefins, aromatics and benzene can be measured by different methods. The characteristics of these methods are compared and analyzed through robin tests. A new method for determination of hydrocarbon types and benzene by multi gas chromatography developed by Research Institute of Petroleum processing （RIPP）is introduced in detail. This method is adopted and published as an international ASTM standard, which is the first international standard set by China in the field of oil and petroleum products.
