摘　　要：采用催化汽油加氢可以使烯烃饱和为烷烃 ,加氢后的汽油利用分子筛吸附分离把正构烷烃从中分离出来 ,可以弥补因加氢造成的辛烷值降低 。The olefin in the FCC gasoline will be converted into paraffin by hydrotreating and then by means of absorption stripping, the normal paraffin in gasoline will be removed,so the octane number in gasoline will be made up,and the content of olefin will be reduced.
