摘要/Abstract

摘要： 以中国石油大连石化分公司第七生产厂的催化裂化油浆为原料，分别以糠醛、复配A作为萃取溶剂，对溶剂抽提精制催化裂化油浆进行研究，考察抽提温度、剂油比对单级抽提的精制效果，优选最佳的抽提条件进行多级逆流抽提试验。结果表明：分别以糠醛和复配A作为萃取溶剂，在抽提温度60 ℃、剂油质量比2～3的条件下，均可以有效地将油浆中的烷烃与芳烃分离，分离效果较好。抽余油（精制油）可作为RME(F)180系列船用残渣燃料油的调合组分，抽出油可作为KA8520橡胶填充油的调合组分。

Abstract: The solvent extraction method can effectively separate the light alkane and the condensed nucleus aromatic in FCC slurry. Furfural and PA (combined solvent) were used as extraction solvent and were compared for separation efficiency. The influence of extraction temperature, mass ratio of solvent to oil was investigated to find the best operation conditions of the multi-stage countercurrent extraction process. The results show that FCC slurry can be separated well at the extraction temperature 60℃, ratio of solvent to oil 2～3. The raffinate oil can be used as the blending component of RME (F) 180 series marine residual fuel oil. The extract oil can be used as the blending component of the KA8520 rubber filling oil.
