Cu基分子筛催化剂抗中毒性能的研究进展

Research progress on the poisoning resistance properties of Cu-based zeolite catalysts

以SAPO-34、SSZ-13和ZSM-5载体为主线,综述了近年来国内外Cu基分子筛的中毒失活机理,以及在制备方法、Cu物种种类和含量、分子筛载体改性对催化剂抗失活性能提升的研究进展,并展望了该领域未来可能的发展方向和研究热点。

SAPO-34,SSZ-13 and ZSM-5 carriers were used as the main line.The mechanism of poisoning inactivation of Cu-based molecular sieves at home and abroad in recent years was reviewed,as well as the preparation methods,the types and contents of Cu species,and the modification of zeolite support to catalysts.The research progress of inactivation can be improved,and the future development directions and research hotspots in this field are expected.
