我国汽油的主要调和组分是FCC汽油,汽油中90%以上的硫和几乎全部的烯烃均来自FCC汽油组分,所以降低FCC汽油中的硫含量和烯烃含量是满足未来汽油质量指标要求的关键.目前,降低FCC汽油硫含量的主要方法是催化加氢脱硫.但是加氢处理方法存在如下问题:①设备投资大,②加氢脱噻吩硫 The major blending component of gasoline in China is FCC gasoline, which contains more than 90% of the sulfur and almost all of the olefins from the FCC gasoline components, so reducing the sulfur and olefin content of the FCC gasoline is the key to meeting future gasoline quality specifications At present, the main method for reducing the sulfur content of FCC gasoline is catalytic hydrodesulfurization, but the following problems exist in the hydrotreating process: (1) equipment investment is large, (2) hydrodesulfurothiophene
