| 摘 要： | 对分子筛孔道清理改性技术在水热超稳分子筛DASY2.0生产中的工业应用情况进行了总结,并用XRF法分析了应用孔道清理改性技术后所生产的DASY2.0工业产品的化学组成,采用XRD、DTA及BET等方法对产品的物化性能进行了系统表征,并和以前未采用孔道清理改性技术所生产的水热超稳分子筛DASY2.0的性能进行了分析对比。结果表明,与水热超稳分子筛孔道清理改性技术工业应用前相比,孔道清理改性技术工业应用后所生产的水热超稳分子筛DASY2.0工业产品的氧化钠含量明显降低,晶胞常数基本相当,结晶度明显提高,比表面积明显增大,热稳定性明显提高,酸量显著增多,裂化活性增强,孔道清理改性技术使得水热超稳分子筛DASY2.0的性能明显改善。

| Abstract: | The pore cleaning modification in the production of ultra-stable zeolites prepared by hydrothermal method was summarized.The industrial products of zeolites before and after the modification were analyzed and characterized by XRF,XRD,BET,DTA and IR methods.The results showed that,in comparison with the conventional ultra-stable zeolite DASY-2.0 prepared by the hydrothermal process,the pore cleaning modified zeolites exhibited lower Na2O content,relative crystallinity,higher surface area and pore volume,improved thermal stability,larger acid amount and better activity. |
