Molecular Sieves

The molecular sieve is a kind of the aluminosilicate. As there are even pore size and much more specific surface in it. It has much excellent merit :1The selective absorption, according to the size and shape of the absorbed molecule, in this way, it absorbs only those molecules whose diameter are less than the molecular sieve pore.2It has the selective absorption for the polar or unsaturated molecles. The higher the polarity or unsaturation is, the stronger selective absorption is.3It has strong water absorption. Even if higher temperature, large flow rate and lower water content, it keeps still higher water absorption. Our company has produced many industry molecular sieves, such as 3A,4A,5A,10X,13X and copper-bearing etc.Main specification of 3ASize Item Φ1.5-1.7 mm Φ3.0-3.3 mm Super grade First grade Qualified Super grade First grade Qualified Abrasion Ratio ≤ 0.25 0.35 0.50 0.60 0.80 1.00 Bulk density ≥ 0.64 0.60 0.55 0.64 0.60 0.55 Grain ≥ 98.0 94.0 90.0 98.0 90.0 80.0 Static water absorption ≥ 20.0 19.0 20.0 19.0Crushing strength ≤ 20.0 18.5 15.0 20.0 18.5 15.0 Static ethane absorption ≤ 3.0 Package water content ≤ 1.5
