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,调整炼油装置结构,降低汽油中烯烃和硫含量,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 n umber 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.
