CHEMXIN Molecular sieves are used as a desiccant of adsorbents for industrial process which require the adsorption and removal of oxycompound elements during industrial processing. Molecular sieves are characterized by the ability to distinguish molecules based on the size of the pore.
Chemxin produces 3A, 4A, 5A, 13X, 13x apg molecular sieve products, can be applied to different industries according to the requirements of different industries on adsorbent.

3A Molecular Sieve
a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
b) Cracked Gas Drying
c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
d) Drying of highly polar compounds, such as methanol and ethanol
e) Drying of liquid alcohol
f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
g) Drying of CNG.
4A Molecular Sieve
a) Drying and removing of CO2 from natural gas, LPG,air, inert and atmospheric gases, etc
b) Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syngas treating).
c) Special types are used in the air brake system of buses, trucks and locomotives.
d) Packed in small bags, it may be used simply as a packaging desiccant.
e) For fire escape mask
g) For filter
5A Molecular Sieve
a) The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S form sour natural gas streams, while mini missing COS formation. Light mercaptans are also adsbored.
b) Separation of normal-and iso paraffin's
c) Production of high purity N2, O2,H2 and inert gases from mixed gas streams.
d) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
13X Molecular Sieve
a) Removal of CO2 and moisture from air (air pre-purification) and other gases.
b) Separation of enriched oxygen from air.
c) Removal of mercaptans and hydrogen sulphide from natural gas.
d) Removal of R-SH and H2S from hydrocarbon liquid streams (LPG, butane etc.)
e) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams)
f) Removal of n-chained compositions from aromatics.
g) Production of bulk oxygen in PSA units.
13X APG Molecular Sieve
a) Removal of CO2 and H2O from air for air cryo-separation application
