SAPO-11 Molecular Sieve

Product Overview
SAPO-11 molecular sieve has an AEL structural type with a pore size of 5.64Å. Its pore channels consist of 10-membered, 6-membered, and 4-membered rings, providing a multi-ring structure. This molecular sieve plays a significant role in petrochemical processes due to its exceptional catalytic properties. It is especially suitable for processes such as the isomerization of n-butene, hydroisomerization of long-chain n-paraffins, catalytic cracking to increase gasoline octane rating, and dewaxing and pour point lowering of lubricating oils. Its unique pore structure provides excellent selectivity and stability in catalytic processes.
