摘　　要：采用提升管催化裂化装置,考察脱沥青油(DAO)以及抽提条件分别为剂油质量比2∶1、抽提温度80℃;剂油质量比2∶1、抽提温度85℃两种工况下对DAO进行糠醛抽提所得到的抽余油A与B等三种催化裂化原料的裂化性能。实验结果表明:DAO经过糠醛抽提后所得抽余油的催化裂化转化率较高,轻质油收率较高,重油和焦炭产率较低,其催化裂化性能和裂化产品的性质均优于DAO。In this paper, pilot plant riser reactor was used to evaluate the catalytic cracking performances of desaphalted oil （DAO） and its raffinate oils （denoted as feed A and feed B）,which were obtained by extracting DAO with furfural under the conditions of furfural/DAO mass ratio of 2,extraction temperature of 80℃ and 85℃ ,respectively. Experimental results indicated that compared with DAO, both feed A and feed B exhibited improved catalytic cracking performances： higher heavy oil conversion and light oil yield,lower yields of coke and slurry oil, besides, the properties of cracking products from feed A and feed B are also better in some ways.
