Abstract:

The study of complex de-nitride in lubricant by furfural and additives was researched for a second-tier base oil in Fushun No.1oil plant, according to single factor experiments, influences on removal rate of the basic nitrogen by temperature and oil/solvent ratio were obtained, finding a more suitable metal additive dosage of 0.50~1.33(mol zinc bromide/mol quinoline).Then through orthogonal test determining the effects on the complex extraction(removal rate of basic nitrogen), the most influential factor is the metal additive dosage, followed by the oil/solvent ratio, temperature minimum. The results show that adding a small amount of zinc bromide can greatly enhance the effect of furfural refining, its basic nitrogen removal rate increases, it greatly increases the effect of furfural extraction.

摘要： 针对抚顺石油一厂的减二线基础油进行糠醛溶剂加助剂络合脱氮研究, 考察反应温度及剂油质量比对碱性氮脱除率的影响规律, 找到较适宜的金属助剂溴化锌与喹啉的物质的量比为0.50 ～ 1 .33 。然后采用正交设计的试验方案确定对络合萃取效果(即碱性氮脱除率)影响最大的因素是金属助剂溴化锌与喹啉的物质的量比, 其次是剂油质量比, 温度的影响最小。由实验结果可以看出, 加入少量溴化锌就可以极大地提高润滑油糠醛精制的精制效果, 其碱性氮脱除率明显增加, 大大提高了糠醛的萃取效果。
