Influence of Synthesis Conditions for ZSM-5 on the Hydrothermal Stability of Cu-ZSM-5
The influence of syntheses parameters of zeolite ZSM-5 on the lean NO (x) reduction activity and hydrothermal stability of Cu-ZSM-5 has been investigated. The hydrothermal stability of Cu-ZSM-5 was found to depend on the aluminium source used and on the presence of Ca(OH)(2) in the synthesis mixture for ZSM-5.
