In-situ Synthesis of ZSM-5 with Different Si/AlRatios on Honeycombshaped Cordierite and their Behavior on NO Decomposition

ICM Department of Chemistry Nankai University Tianjin 300071

Received Date: 19 May 1999

Zeolites ZSM-5 with different Si/Al ratios were in-situ synthesized on the surface of honeycomb-shaped cordierite support for the first time. Characterizations of XRD and SEM were performed and it has been proved that the zeolite ZSM-5 was grown on the surface of the cordierite homogeneously. NO decomposition on the Cu exchanged ZSM-5/cordierite monolith catalysts was also studied. It was found that the monolith catalysts have a fine initial activity at 673K and GHSV of 10,000h^-1. Such method should be a good way to make auto exhaust converter with monolith catalyst for NOx removal.
