A comparative study on the structural and catalytic properties of zeolites type ZSM-5, mordenite, Beta and MCM-41

Zeolites of different structures and textural mesoporosity (ZSM-5, mordenite, Beta and MCM-41) were investigated as catalysts in liquid phase isomerization of alpha-pinene at 373 K and in methanol conversion. The morphological characterization of the samples was fulfilled before and after the reaction by XRD, SEM, BET and temperature programmed desorption of ammonia.

Zeolites of different structures and textural mesoporosity (ZSM-5, mordenite, Beta and MCM-41) were studied. Zeolite framework irregularity, mesoporosity and acid sites dispersion had a major influence on the reactions as alpha-pinene isomerization and methanol conversion. Acidify is the governing factor for alpha-pinene isomerization in comparison with samples mesoporosity. Figure optionsDownload as PowerPoint slide
