SAPO-11

Name：SAPO-11
Crystal Structure：AEL
Pore Size ：5.64Å
Ring Sizes： Ten-membered ring、Hexatomic ring、Four-membered ring

Product name: SAPO-11

Description:

SAPO-11 molecular sieve has AEI structure and belongs to the orthogonal crystal system. Its skeleton is mainly formed by tetrahedron interweaving with each other being composed of P\SI\AL atoms and has an elliptic Ten-membered ring and a one-dimensional straight ring channel. Because of its weak acidity, it is often used in catalytic cracking reaction in petrochemical industry to improve the octane number of gasoline.

Applications:

1.Low carbon olefin isomerization

2.It is used to prepare catalysts for catalytic cracking to improve octane number of gasoline and for hydroisomerization and dewaxing of lubricating oil.

3.Isodewaxing of diesel and base oil

4.Iron or cobalt catalysts are used in combination with SAPO-11 molecular sieves to convert syngas into gasoline components above C5, improving process selectivity and product quality

5.Alkylation of aromatic hydrocarbons with branched group
