4A Molecular Sieve for Water Purification and Drying Systems
The main component of silica gel is SiO2. The components of molecular sieves can be SiO2, SiO2-Al2O3, SiO2-B2O3, or SiO2- other metal oxides. Molecular sieves are used to separate molecules of different molecular weights. Silica gel generally separates acidic compounds. The difference in acidity between the two is also significant.
13X Molecular Sieve Adsorbent Molecular Sieve Zeolite for Catalyst Carrier Zeolite 13X Molecular Sieve
13XMS
Features:
13X APG Molecular Sieve, is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 9 angstrom(0.9nm) and exclude those larger.
It have the highest capacity of the common adsorbents and very good mass transfer rates.
It can remove impurities too larger to fit into a type A crystal and is commonly used to separate N2 from O2.
Chemical Molecular Formula: Na2O·Al2O3·2.45SiO2·6.0H2O. (SiO2:Al2O3≈2.6-3.0).
Applications: Removal of H2O from air for air cryo-separation application.

3A Molecular Sieve High Quality Desiccant 3A Zeolite Price Molecular Sieve Adsorbents for Gas Drying
3AMS
Features:
3A Molecular Sieve, is an alkali metal alumina silicate. It is the potassium form of the type A crystal structure.It has an effective pore opening of about 3 angstroms(0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form
polymers.
