Zhongci 20 Years China Brand High Adsorption Zeolite 4A Molecular Sieve as Desiccant

Molecular Sieve 4A, also called zeolite 4A or zeolith 4A, is one type of aluminosilicate crystal with average pores measuring 4 angstroms (0.4 nm). Molecular with kinetic diameter smaller than 4 angstroms will be adsorbed by zeolite 4A, otherwise, be excluded.4A molecular sieves are typically used for dehydration in the air brake systems, natural gas drying.

The effective pore size of 4A molecular sieve is 0.4nm, so it is called 4A molecular sieve

Zhongci Molecular Sieve 4A is an alkali aluminum silicate with a pore size of 4 angstroms. It adsorbs most molecules with a kinetic diameter smaller than 4 angstroms and excludes those larger.

4A molecular sieve desiccant has good drying ability to various solvents, adding molecular sieve to the solvent can effectively ensure that the solvent maintains a low water content.

Molecular sieve adsorbent can also be packed in individual desiccant bags to protect electronic equipment, pharmaceuticals, food, ship cabins, containers and other systems from the threat of moisture accumulation and mildew.

Application:
1) Static Drying in Gas Stream Liquid;
2) Drying and removing of Co2 from Natural Gas Processing and Liquefied Natural Gas(LNG);
3) Ammonia and Syngas Treating;
4) Industrial Desiccant Air Dryer;
5) Refrigerants Drying;
6) Static drying of electronic components.

Chemical Molecular Formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O. (SiO₂ : Al₂O₃ ≈2).
