摘要
选取四类不同的复合溶剂，依据萃取理论，运用正交设计方法，针对咸阳助剂厂生产的催化裂化柴油进行了精制工艺研究．试验结果表明，催化裂化柴油经优选的复合溶剂精制后，柴油收率达９５％ ，且可脱除约７１．７％ 的总氮、７３．７％ 的非碱性氮、４６．９％ 的硫醇和５４．１％ 总硫．精制后的催化裂化柴油进行加速储存后色度为１３＃ ，达到一级柴油标准的要求，稳定性提高，溶剂可以回收循环使用．
Based on extraction theory, the extraction technology of catalytic cracking diesel is studied by four complex solvents in orthogonal experiments.The diesel used in the experiments is made in Xianyang Auxilary Factory. The experimental results show that, after the diesel is extracted by optimum extracting solvent, its extraction efficiency reaches to 95%, and 71.7% of total nitrogen, 73.7% of non basic nitrogen, 54.1% of total sulfur and 46.9% of mercaptan sulfur can be removed from LCO. The storage test also shows that the stability of LCO is improved evidently after extraction, colour mumber is also increased from 11 # to 13 #,and the solvent can be retrieved and reused.
