摘要
同发达国家相比,我国在清洁汽油的具体指标方面还存在较大差距,汽油质量始终面临着蒸气压高、辛烷值分布差,尤其是烯烃含量过高的压力,长远看,硫、苯、氧等指标含量也将面临着更大压力。结合我国汽油生产现状,调整炼油厂装置构成,降低我国汽油中的烯烃和硫含量,将是我国汽油中长期发展的方向。
Compared with developed countries, the quality indexes of clean gasoline produced by China have big gap, such as high steam pressure, octane number distributing, and high content of olefin. In the future,gasoline of China will face bigger pressure because of sulfur, benzene and oxygen content. Based on the production situation,middle and long-term development direction of gasoline in China is adjusting equipment of oil refining and reducing the content of olefin and sulfur.
