3A, 4A & 5A Molecular Sieves

Molecular Sieve 5A

5A molecular sieve is a calcium-form A-type zeolite adsorbent with an effective pore opening of approximately 5 angstroms. It adsorbs normal (straight-chain) paraffins and small polar molecules, and is used in separation and purification duties where selective adsorption is required.

Applications
  • Separation of normal paraffins from branched-chain and cyclic hydrocarbons
  • Pressure swing adsorption for hydrogen purification
  • Removal of water, carbon dioxide and hydrogen sulfide from gas streams
Product Selection For product selection, provide the feed composition, the impurities to be removed or the component to be separated, operating pressure and temperature, flow rate, target outlet specification, and required loading quantity.

Molecular Sieve 3A

3A molecular sieve is a potassium-form A-type zeolite adsorbent with an effective pore opening of approximately 3 angstroms. It adsorbs water and other small polar molecules while excluding most hydrocarbons, which makes it a standard choice for deep drying of gases and liquids.
