On the Separation of Chloronitrobenzene Isomers in HZSM-5 Zeolite Fixed-Bed Reactor

  • 摘要: 以Al2O3为粘结剂对粉末状HZSM-5分子筛成型,并通过HZSM-5分子筛固定床分离水体中硝基氯苯异构体.研究流量对分子筛固定床动态吸附与温度、流量对固定床动态脱附的影响,得出其动态吸附-脱附最优化条件:吸附流量25 mL/h;处理量1.35 L/批次;脱附温度40 ℃;脱附流量10 mL/h.设计了双柱串联吸附实验,以直接高效分离水体中的对硝基氯苯与邻硝基氯苯.结果表明,采用双柱串联吸附-脱附工艺,可从硝基氯苯混合液中同时回收纯度高于95%的对硝基氯苯和邻硝基氯苯,且动态吸附-脱附实验具有较好的重现性.
