摘　　要：催化裂化回炼油浆富含重芳烃,经糠醛精制后,抽出油可用于生产橡胶填充油,同时抽余油可作为催化裂化原料回炼,回炼油浆得到充分利用.本实验采用纯糠醛为溶剂对石油二厂催化裂化回炼油浆进行了芳烃抽提小试考察.实验结果表明,以纯糠醛为溶剂抽提回炼油浆最适宜的操作条件:剂油比为1:1(质量比),抽提温度为65℃.此时抽余油的收率为61 36%,饱和分含量由回炼油浆的40 62%提高到62 16%;抽出油的收率为38 64%,芳烃加胶质的百分含量大于90%.Catalytic cracking cycle slurry is rich in heavy arenes and can be applied to produce filled oak oil after furfural refining. Raffinate oil can also be used as catalytic cracking feedstock. Cycle slurry can be used fully. The aromatic extraction laboratory scale test about No.2 refinery's catalytic cycle slurry was done with the pure furfural. The experimental result shows that the fitting operation conditions of the pure furfural used as solvent were as following:the ratio of solvent/oil was1:1 (weight) and the temperature of the extraction was 65 ℃. The yield of the raffinate oil was 61.36%, of which the saturated constituents were increased from 40.62% to 62.16%; and the yield of extract oil was 38.64%, of which the aromatic and resin constituents were over 90%.
