| 摘 要： | 用双溶剂萃取法提高催化裂化柴油的十六烷值，即用含有金属离子的糠醛作第一溶剂对催化裂化柴油中的双环以上芳烃进行萃取，再用石油醚对抽出油进行萃取以回收其中的高十六烷值组分。结果表明，经该方法处理所得到的合格柴油收率可达90％。糠醛中溶有金属离子可提高对双环以上芳烃及氮等杂原子化合物的选择性，从而提高催化裂化柴油的十六烷值和安定性。

| Abstract: | Bi-solvent extraction for improving LCO cetane number was studied in the laboratory. Metal ion contained furfural was used as the first solvent for extraction of the 2-ring aromatics and heavier, and petroleum ether was used as second solvent to recover the high cetane number component from the extract oil. the upgrading LCO recovery reached 90% and its cetane number and oxidation stability were improved. |
