What is Mordenite?

Mordenite is a crystalline aluminosilicate zeolite with the MOR framework topology. It contains one-dimensional 12-membered ring main channels and smaller 8-membered ring side pockets, giving it a large-pore but diffusion-constrained structure.

In catalyst procurement, Mordenite is usually discussed as Na-Mordenite, NH4-Mordenite, or H-Mordenite. Na-Mordenite is a precursor or adsorbent form. NH4-Mordenite is calcined by the user to generate H-form. H-Mordenite provides strong Brønsted acid sites for acid-catalyzed reactions.

Mordenite is evaluated for alkylation, isomerization, dehydration, adsorption, and as an acidic support in selected hydrocarbon conversion catalysts. Compared with Beta zeolite, Mordenite has a more constrained one-dimensional channel system. Compared with Y zeolite, it lacks FAU supercages and therefore behaves differently in bulky-molecule diffusion.
