SAPO-11 molecular sieve has AEL structure, belongs to orthorhombic system, and the space group is Ima2. Its skeleton is mainly formed by A1O2-, PO2+, SiO2 tetrahedron intertwined with each other, and has an elliptical ten-membered ring one-dimensional straight channel.
Due to its weak acidity and suitable pore size, SAPO-11 has high activity and selectivity in reactions such as n-butene isomerization and long-chain n-paraffin hydroisomerization. It is used in catalytic cracking to improve gasoline octane number. It has laid a foundation for the application in petroleum refining and petrochemical processes such as hydrodewaxing and pour point reduction of lubricating oil.Morphology: Powder |
