摘要
由于国内对汽油辛烷值和低碳烯烃的需求，ZSM－5一类具有中等孔径的择形沸石越来越大量地应用于催化裂化过程中。讨论了HZSM－5沸石在催化裂化过程中的停用，以及性能改进的途径，并介绍了一种具有良好水热稳定性的中孔择形沸石ZRP。在催化裂化过程中ZRP沸石催化剂对于提高汽油辛烷值和低碳烯烃的生产较HZSM－5佛石催化剂更为有利。
ZSM-5 series medium-pore shape selective zeolite catalysts are increasingly used incatalytic cracking processes due to domestic demands for gasoline octane number and gaseous olefins. Thefunctions of HZSM-5 zeolite in FCCU and its performance improvement are discussed. A new type ofmedium-pore shape selective zeolite with good hydrothermal stability, ZRP, which is much better thanHZSM-5 for gasoline octane enhancement and gaseous olefin production, is introduced.
