SAPO-11 Zeolite,Zeolite SAPO-11,SAPO-11Molecular Sieve
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 belongs to one dimension pore structure. This type of micro pore zeolite has low activity in cracking and disproportionate, high activity in isomerization and alkylation , excellent anticokability. It has high selectivity of para-position in isomerization of xylene and methylization of toluene. SAPO-11 zeolite can be used as catalyst or catalyst carrier for dewaxing via isomerization, selective hydrogenation, cracking, condensation of alcohol and aldehyde, etc.
SiO2/Al2O3 Mole Ratio: 22
Na2O Weight %: 0.05
