摘要
采用复合溶剂萃取催化裂化柴油中的氮化物,提高柴油的氧化安定性。实验室研究结果表明,在室温,剂油比为0.5～0.75∶1,3级逆流萃取精制柴油,精制油氮化物脱除率达94％,收率超过95％,色度、氧化安定性均达到一般柴油标准。溶剂可回收循环使用。
The nitride of compasite solvent extraction FCC LCO has been adopted, and improving the oxidation stability of FCC LCO. The laboratory test indicated that the removal of the nitride of the refined LCO exceeded 94%, and the yield of the refined LCO was more than 95 % , the both of colority and oxidation stability met the national standard of grade A LCO under indoor temperature, and volume ratio of solvent to oil of 0.5-0.75:1, in three stages adverse current extraction FCC LCO. The solvent can be retrieved and circulated use.
