Molecular Sieve

Molecular Sieve Beads Type 4A This bag contains both blue moisture indicating molecular sieve and also normal molecular sieve. The blue molecular sieve is a sodium alumina silicate molecular sieve impregnated with an inorganic metal salt moisture indicator. The desiccant will perform as a 4a molecular sieve plus with the additional ability to visually determine when the molecular sieve reaches saturation. When active, the molecular sieve beads are blue, as the beads reach saturation the color changes to beige indicating that the molecular sieve has reached equilibrium capacity and is in need of replacement. While the white molecular sieve is an alkali alumino-silicate in the spherical form. It is the sodium form of the Type A crystal structure with an effective pore opening of approximately 4A. It will adsorb molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Aromatics and branched chain hydrocarbons will not be absorbed. Key Features: Natural Gas Drying The desiccant is known to act as a molecular sieve with the bonus ability to tell visually when the molecular sieve achieves saturation A sodium alumina silicate molecular sieve with inorganic metal salt moisture indicator Dehydration of highly polar compounds, such as methanol and ethanol More efficient than older silica gel and alumina desiccants Crystalline composition Ease of Use Molecular Sieve 4A Technical Data Sheet Molecular Sieve 4A Safety Data Sheet Specifications: Type: 4A Bead Size: 4mm Includes Blue moisture indicating beads Nominal Pore Opening: 4 Angstroms Equilibrium Water Capacity @ 25°C: >= 22% Weight Heat of Adsorption: 1800 BTU/lb of H2O Note: 20lb size comes as set of 2x 10lb containers.  Size Recommendations: 2LB - Will fit our Molecular Sieve Filter Drier 4LB - Will fit our XL Molecular Sieve Filter Drier

Molecular Sieve Beads Type 13X  13X molecular sieve is a multiple purpose, highly porous, high capacity alkali metal alumino-silicate in the spherical form. It is the sodium form of the Type X crystal structure with pore diameters of approximately 10A. It can adsorb all molecules that can be adsorbed by 3A, 4A, and 5A molecular sieve. Type 13X molecular sieve can also adsorb molecules such as aromatics and branched-chain hydrocarbons, which have large critical diameters. Handling & Storage Recommendations: Store in a dry location to prevent unintentional water adsorption. Reseal packages after opening to prevent contamination and unintentional water adsorption. We recommend that you rotate stock so oldest material is used first. Please read the safety data sheet to ensure proper handling and always wear personal protection equipment when handling molecular sieve.

Ethanol Dehydration Sieve Beads Type 3A Ethanol Dehydration Beads Type 3A is specifically designed for the dehydration of fuel grade ethanol. Ethanol can only be dried to an azeotropic point of 95.6% purity by traditional distillation. After that point, 3A selectively adsorbs the water from the solution to produce anhydrous ethanol with less than 0.5% water. This is the drying method of choice for fuel ethanol producers.  With these beads you can remove water to achieve a metered proof of 200 or 99.999%.  Chemical Formula: K12[(AlO2)12(SiO2)12] · nH2O. Typical Applications: Ethanol Dehydration Grade Molecular Sieve products (sieve beads) are typically used for the dehydration of fuel grade ethanol PSA and VSA systems. Available Products Ethanol Dehydration Grade Molecular Sieve: Product Adsorbent Type Size Form 3A EDG Molecular Sieve 3A 4 x 8 Mesh Beads Handling & Storage Recommendations: Store in a dry location to prevent unintentional water adsorption. Reseal packages after opening to prevent contamination and unintentional water adsorption. We recommend that you rotate stock so the oldest material is used first.

Indicating Molecular Sieve Beads TYPE 4A (Blue) Description: 4A Blue Indicating Molecular Sieve is a porous, high capacity alkali metal aluminosilicate compound. Like non-indicating 4A molecular sieve, our blue indicating 4A molecular sieve has 4 Angstrom-sized pore openings that allow to adsorb all molecules adsorbed by 3A,  molecular sieve, plus larger molecules like aromatic and branched-chain hydrocarbons. Handling & Storage Recommendations: Store in a dry location to prevent unintentional water adsorption. Reseal packages after opening to prevent contamination and unintentional water adsorption. We recommend that you rotate stock so the oldest material is used first. Please read the safety data sheet to ensure proper handling and always wear personal protection equipment when handling molecular sieve.  Molecular Sieve 4A Indicating Technical Data Sheet  Molecular Sieve 4A Indicating Technical Data Sheet
