Description générale

Molecular Sieve, Type 3A is a synthetic crystalline aluminosilicate (potassium form crystal structure or type A zeolite) with an effective pore diameter of 3 Å. It is used as an effective adsorbent. It adsorbs molecules having a kinetic diameter of less than 3 Å and excludes molecules with a kinetic diameter of greater than 3 Å.[1][2][3]

Application

Molecular Sieve, Type 3A can be used:
  • As a selective adsorbent for the adsorption of water and ammonia.[4]
  • In drying polar liquids such as methanol and ethanol.[2][4]
  • In commercial dehydration of unsaturated hydrocarbon streams, including cracked gas, propylene, butene, and natural gas.[5][6][7]

Questions

1–2 of 2 Questions  

  1. Are this 3A molecular sieves food grade?

    1 answer

    1. No, this product is not food-grade. Currently, a food-grade product option is not available.

  2. Is there a regeneration procedure for these Molecular Sieve dessicants ?

    1 answer

    1. Molecular sieves can be dried in a drying oven above 250°C to a water content of 2-3 g/100 g. The remaining water can be removed at 300-350°C using a vacuum oil pump (10-1-10-3 mbar), whereby, as is usual, a cold trap containing carbon dioxide coolant or liquid air should be connected. Water pumps, due to their high partial water vapor pressure, are completely unsuitable for this purpose. For safety reasons, molecular sieves that have been used to dry solvents should be freed from possible solvent by mixing with water before regeneration. This can be carried out as often as required; the maximum regeneration temperature is 450°C.
