【摘要】：欧盟国家汽柴油质量标准走在全球前列,是全球最多的被其他国家借鉴、参考或者采用的标准。从欧盟汽柴油质量标准的变化可以看出,硫含量是汽柴油变化幅度最大的指标,汽柴油硫含量降至10ppm以下基本是国际趋势;从欧盟实际销售的汽柴油质量看,汽油质量的合格率明显高于柴油,由于柴油用途广泛,对柴油标准的制定更应周全;辛烷值不达标是汽油不合格的主要表现之一,这是包括我国在内的许多国家汽油质量升级面临的挑战;欧盟使用乙醚代替乙醇,从而避免了汽油蒸汽压的增高,同时对汽油氧化物含量进行严格控制及详细规定。我国正加速提高国内汽柴油品质,与欧盟油品质量的差距已经越来越小,如果实施到位,必将对我国空气质量改善做出贡献。
[Abstract]:The standard of the European Union countries' gasoline and diesel quality standards is in the forefront of the world, which is the most widely used standard in the world for reference, reference or adoption by other countries. From the change of quality standard of European Gasoline and diesel oil can be seen, the sulfur content of gasoline and diesel is the largest index variation, the sulfur content of gasoline and diesel to below 10ppm is international trend; from the actual sales of gasoline and diesel quality, the qualified rate of the gasoline quality was significantly higher than that of diesel, diesel due to a wide range of uses, to make diesel standards more should be comprehensive; octane gasoline is one of the main performance standards are not qualified, this is the challenge in many countries including China to upgrade the quality of gasoline; the use of ether instead of alcohol, so as to avoid the increase of gasoline vapor pressure, and strictly control and detailed regulations on gasoline oxide content. Our country is accelerating the improvement of the quality of domestic gasoline and diesel, and the gap between the quality of gasoline and the European Union has been getting smaller and smaller. If implemented, it will contribute to the improvement of air quality in China.
