Mesoporous Molecular sieve MCM-22 zeolite is a novel microporous molecular sieve with MWW structure. In the molecular sieve layered structure of the upper and lower surfaces are covered with a high density of the hole structure, the whole structure for the twelve yuan ring opening, the depth of about 0.7 nm.
Parameters of MCM-22 Zeolite
|Na + content（%）||≤0.1|
|Specific surface area (m2 / g)||550-800|
|Hole capacity (cm3 / g)||0.15~0.50|
|Phosphorus and aluminum ratio||20~70|
|Residual sodium (%)||≤0.1|
