页岩油脱碱性氮化合物的研究

以抚顺页岩油为原料,加入脱氮试剂脱除碱性氮化物,考察络合反应温度、络合反应时间、剂油体积 比、络合剂与溶剂的体积比对碱性氮脱除率及精制油收率的影响。最佳的操作条件为:温度55~60 ℃,络合反应时 间5min,剂油体积比为0.07,络合剂与溶剂的体积比为1∶0.5~1∶1,静置时间35min,在此条件下,碱性氮脱除率 可达95.36%,精制油收率为91.25%。结果表明:选取的复合溶剂能有效脱除碱性氮化物,经试剂B处理后的页岩 油pH 为中性。

Removal of Basic Nitrogen Compounds From Shale Oil

The basic nitrogen-compounds were removed with complexation by denitrification reagent form the Fushun shale oil.The effect of reaction temperature,reaction time,volume ratio of agent to oil,complexing agent amount and settling time on the denitrification ratio and yield were investigated.The optimum operating conditions are as follows: The temperature 55~60 ℃,reaction time 5 min,volume ratio agent and oil 0.07,auxiliary usage 1∶0.5~1∶1,motionless time 35 min.Under these conditions,the denitrification ratio and oil yield can reach 95.36% and 91.25%,respectively.The results show that mixed solvent could be used in denitrification with high efficiency,pH of the shale oil dealed with reagent B is neutral.
