ZSM-22 zeolite has a topological skeleton of ton structure that contains five membered ring and six membered ring as well as ten membered ring. 1D channels which consists of ten membered ring is a non-intersect Parallel channels whose orifice is oval.
Application: ZSM-22 channel can restrain carbon deposition, and has a strong selectivity for small molecule reactions. Due to its suitable pore structure and strong surface acidity, it can be used in catalytic cracking, hydrocracking, dewaxing , isomerization (such as paraffin isomerization and butene skeletal isomerization), alkylation, dealkylation, hydrogenation, dehydrogenation, dehydration, cyclization ,aromatization mechanism and soon.
