Introduction
      Molecular Sieve type 4A (Angstrom) is an alkali alumino silicate, obtained through synthesis of type A zeolite in sodic form. it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Galaxychem type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

Typical application:

       Will absorb, in sequence of absorption rate, argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.

  • Deep drying of air, natural gas, alkane and refrigerant.
  • Generation and purification of argon.
  • Static dehydration of electronic element, pharmaceutical and unstable materials.
  • Desiccant of paint, PU Plastic, dope and fuel etc.

Formula: 4ANa2OAl2O32SiO24H2O

Regeneration
     Molecular Sieve 4A can be revived for reuse and the required factors for revival are temperature and pressure. To remove the adsorbed moisture and other materials, the revival condition shall be set up considering   the features of target material and processing environment. The general revival temperature of Molecular Sieve 4A is about 300°C and it should   not surpass 450°C at maximum.
