(41a) Tailoring Zeolite ZSM5 Crystal Morphology and ...

The micropores of large zeolite crystals often impose severe mass transport limitations that adversely affect catalyst activity. 1 One of the challenges in zeolite design is to predictively control crystal size and habit to improve molecular diffusion. Here, we present a novel approach to tailor ZSM5 crystallization using zeolite growth modifiers (ZGMs), which are molecules that bind to ...

Zeolite structure and types Lenntech

Synthetic zeolites have a silica to alumina ratio of 1 to 1 and clinoptotilite (clino) zeolites have a 5 to 1 ratio. Clino natural zeolites do not break down in a mildly acid environment, where synthetic zeolites do. The natural zeolite structure has more acid resistant resistant silica to hold it’s structure together.
