ZSM-22 Formula |Ca₆ (H₂O)₄₀| [Al₁₂Si₂₄O₇₂]-CHA

 

 

ZSM-22 channel can inhibit the production of carbon deposition and has a strong shape selectivity for small molecule reactions.

ZSM-22 has the topological skeleton of TON structure, which includes Five-membered rings, Six-membered rings and Ten-membered rings at the same time. The one-dimensional channel composed ofTen-membered rings is a parallel channel that is not cross-linked and the hole mouth is elliptic.

 

 

Items	Unit	Specification
Appearance	mm	White powder
SiO2/Al2O3 (molar ratio)	%	60-100
BET Surface area	m2/g	≥180
Relative crystallinity	%	≥95

 

 

 

Due to ZSM-22 suitable pore structure and strong surface acidity, ZSM-22 can be used in catalytic cracking, hydrocracking, dewaxing, isomerization (such as paraffin isomerization and butylene skeleton isomerization), alkylation, dealkylation, hydrogenation, dehydrogenation, dehydration, cyclization and aromatization.
