摘要:

研究了我国柴油产量和消费量变化趋势以及不同来源柴油性质与国Ⅵ柴油标准差异,并分析了我国柴油池构成、质量现状和存在的问题。结果表明,在柴油质量升级中,我国面临的最主要压力是如何解决柴油的密度和十六烷值(包括十六烷指数)达标问题,而非柴油的硫质量分数。为此,提出了明确十六烷值和十六烷指数的区别、做好原油加工优化、对劣质柴油进行加氢转化以及调整炼厂产品结构等应对措施。

关键词: 柴油, 质量升级, 密度, 十六烷值, 十六烷指数

Abstract:

This paper compared the variation trend of the output and consumption of diesel and the difference of the qualities of different sources diesel with the standard of Ⅵ diesel in China, and analyzed the composition, quality and problems of diesel pool in detail. It is considered that the most important problems in diesel quality upgrading process is how to reach the standard of diesel density and cetane number (including cetane index), rather than diesel sulfur content. Therefore, some countermeasures were put forward, such as identify the difference between cetane number and cetane index, optimizing crude oil processing, hydro?converting inferior diesel and adjusting the product structure of refinery.

Key words: Diesel, Quality upgrading, Density, Cetane number, Cetane index
