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