Synthesis SAPO-11 Molecular Sieve As Catalyst Carrier For Dewaxing

SiO2/Al2O3 Mole Ratio: 22

Na2O Weight %: 0.05
P2O5:AL203:SIO2:1:1:0.5
Size:1-2um

SAPO-11 molecular sieve having the AEL structure, the orthorhombic space group Ima2. Its skeleton is mainly composed of A1O2-, PO2 +, SiO2 tetrahedron are intertwined and which has an oval 10-MR one-dimensional straight channel.

SAPO-11 due to the weak acid and having a suitable aperture in the long-chain n-butene isomerization and hydroisomerization of normal paraffins and other reactions that have high activity and selectivity for the FCC to increase gasoline octane lubricants and other critical hydrogen dewaxing petroleum refining, petrochemical and process application basis.
