摘要
将抚顺页岩油减压蒸馏得到200～250℃馏分油,采用SH/T0162-92和C2BE30003-861的标准,滴定页岩油馏分油中碱性含氮化合物含量,用预处理后树脂D001cc、树脂D72和树脂D61在室温下进行模拟平推流树脂脱氮,树脂D001cc和树脂D72的碱氮脱除率达95%以上。在模拟全混合树脂脱氮条件下,树脂D72和树脂D61的脱氮率和收率最佳。将模拟平推流洗脱树脂和模拟全混合洗脱树脂与预处理后树脂进行解盐交换量对比,树脂D001cc和树脂D72洗脱前后解盐交换量变化较小,两种树脂经洗脱后可反复利用。
Distillate of 200—250 ℃ was collected by vacuum distillation of Fushun shale oil,and the non-hydrogen denitrification by resins were studied.Three kinds of resins,D001cc,D72 and D61,were used to treat the distillate of shale oil,and the contents of basic nitrogen compounds were determined according to standard SH/T0162-92 and C2BE30003-861.In case of imitating plug flow elution denitrification,the denitrification rates of D001cc and D72 are above 95%.Both denitrification rate and yield of D72 and D61 are good in imitation the total-mixing elution.The exchange capacities of salt solution before and after the treatment were compared both in case of the imitation plug flow elution and the imitation plug flow elution.The exchange capacities of salt solution of D001cc and D72 kept almost unchanged,which showed these two resins could be reused by elution.
