摘　　要：对已运行的MIP装置汽油辛烷值进行统计和汽油加氢试验。统计数据表明,MIP系列技术的汽油辛烷值明显高于FCC汽油的辛烷值;汽油加氢试验结果表明,MIP汽油经加氢后辛烷值损失明显低于FCC汽油。通过对MIP和FCC汽油进行组成分析,发现MIP汽油中含有较多的多支链烯烃、异戊烷和异己烷,基于碳六烃的辛烷值模型可以定量地解释MIP汽油辛烷值高和加氢MIP汽油辛烷值损失低的原因。Data of octane number of naphtha from running MIP units were collected and analyzed in this paper. The statistical data showed that the octane number of MIP naphtha was higher than that of FCC naphtha. Naphtha samples from MIP process and FCC process were hydrotreated on a RSDS-]] unit respectively and the test results showed that as compared with the hydrotreated FCC naphtha, the octane loss of hydrotreated MIP naphtha was lower. It was found that more branch-2 olefin and C5--C6 isoparaffin molecules existed in MIP naphtha. The cause of MIP naphtha having higher octane number and less octane loss during hydrotreating could be explained by the octane model of C6 hydrocarbons quantitatively.
