The framework topology of ZSM-22: A high silica zeolite
1985年11月1日 · ZSM-22, an orthorhombic high silica zeolite (Cmcm, a = 13.86 ± 0.03Å, b = 17.41 ± 0.04Å, and c = 5.04 ± 0.02Å), has a framework consisting of 5-, 6- and 10-rings. The structure contains ferrierite sheets of the type previously found in ZSM-5, ZSM-11 and ZSM-35 and sheets of 6-rings similar to those of the rare zeolite bikitaite.
The synthesis of hierarchical ZSM-22 zeolite with only the PHMB ...
2024年2月1日 · The ZSM-22 zeolite has become an effective support for the hydroisomerization of n-alkanes due to its one-dimensional pore structure, good hydrothermal stability and simple synthesis process. However, the diffusion resistance of hydrocarbons in the microporous channel still limits the further industrial application of the traditional ...
Design and synthesis of Ga-doped ZSM-22 zeolites as highly …
Ga-Doped ZSM-22 zeolites were synthesized successfully via a hydrothermal method by directly incorporating Ga species into the zeolite framework. It appeared that the as-prepared Ga-substituted zeolites possessed high crystallinity, uniform morphology and open pore structure.
