摘　　要：在中型提升管试验装置上考察了回炼低辛烷值汽油及工艺条件对催化裂化产品产物分布及性质的影响,结果表明:在中型提升管评价装置上,不同的回炼比、不同的停留时间以及不同原料条件下,低辛烷值汽油的回炼并没有对产品分布造成较大影响,但是影响了汽油的性质,使汽油产品中的烯烃有所降低,通过此实验实现了对含低辛烷值汽油的再利用,并且能够较大程度地提高其辛烷值。The effects of low octane gasoline and process conditions on the product distribution and properties of FCC products were investigated on the medium-sized riser test unit. The results showed that the product distribution was not greatly affected by the recycling of low octane gasoline under different recycling ratio, residence time and raw material conditions. However, the properties of gasoline was affected, and the olefins in gasoline products reduced.Through this experiment, the reuse of gasoline with low octane number was realized, and its octane number was greatly improved.
