Want to buy bulk molecular sieve onboard ? This ultimate solution guide would help you everything about wholesaling molecular sieve products.

What is Zeolite Molecular Sieve ?

A molecular sieve, also called zeolite, is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.

Depends on zeolite molecular sieve average pore size, the molecular sieve can be classified into molecular sieve 3A, molecular sieve 4A, molecular sieve 5A, molecular sieve 10X and molecular sieve 13X and others. There are also some specially designed molecular sieves by exchanging the metal ion and silica alumina ratios.

With these special properties, the zeoltie molecular sieve are widely used in various areas such as air dehydration, gas dehydration, ethanol dehydration, air break system, refrigerant dehydration, insulating glass system, PSA hydrogen purification, etc.

XIAOYOU is profession in molecular sieve industry for more than 10 years. We are expert to in molecular sieve production and application and can give you the guidlines of how to choose the right and economic molecular sieves for your requirement.

Molecular Sieve 3A

Molecular sieve 3A refers to potassium type A aluminosilicate. Molecular sieve 3A can adsorb molecules with critical diameter less than 3 angstrom. Since molecular sieve 3A can only adsorb water, HF other than other molecules, it is often used in:

Drying of ethylene, propylene, butadiene, etc.
Drying of methanol ethanol, etc.
Insulating glass industry
Refrigerant drying desiccant

Molecular Sieve 4A

Molecular sieve 4A refers to sodium type A aluminosilicate. Molecular sieve 4A can adsorb molecules with critical diameter less than 4 angstrom, such as water, methanol, hydrogen sulfide, carbon dioxide, sulfur dioxide, ethylene, propylene, etc. All molecules that can be adsorbed on molecular sieve 3A can be adsorbed on molecular sieve 4A. It is widely used in:

Removing of carbon dioxide, ammonia and methanol from the gas stream.
Drying and purification of hydrocarbons, such as natural gas, LPG, air, inert gas and atmosphere.
Drying of electronic components and medcine.

Molecular Sieve 5A

Molecular sieve 5A refers to calcium type A aluminosilicate. Molecular sieve 5A can adsorb molecules with critical diameter less than 5 agstrom. All the molecules that can be adsorbed on 3A and 4A molecular sieves can be adsorbed on 5A molecular sieves. It is used in:

Removal of impurities such as H2O, CO2 and acetylene in feed gas of air purification system.
Separation of normal and isoalkanes (C4 ~ C6 fraction) in paraffin industry.
Deep drying and purification of air, O2, N2, H2 and mixed gases.
Purification and drying of oil and natural gas, ammonia decomposition gas and other industrial gases and liquids.
Purification and separation of inert gas.

Molecular Sieve 10X

Molecular sieve 10X refers to calcium type X aluminosilicate. It is often used in:

Remove aromatics, nitrides and sulfides in paraffin refining process.
Deep removal of trace amount of nitrogen oxides and light hydrocarbons in air purification system.

Molecular Sieve 13X

Molecular sieve 13X is a sodium alkali aluminosilicate has an effective pore size of 10 Angstrom and can adsorb molecules less than 10 Angstrom. It can be used in:

Dehydration and desulfurization of natural gas, liquefied petroleum gas and liquid alkanes (propane, butane, etc.).
Purification of gas, removal of H2O, CO2 and hydrocarbon in air separation unit;
Deep drying of general gases (such as compressed air, permanent gas).
Drying and purification of ammonia synthesis gas.
Desulfurization and deodorization of aerosol propellant.
CO2 removal from cracking gas.

What is Oxygen Molecular Sieve ?

Pressure Swing Adsorbtion (PSA) is the most commonly used non-cryogenic oxygen production process, most effective for small and medium capacities. The process operates by using two columns filled with molecular sieve. Pre-treated compressed air enters the first column and follows up through the Zeolite. Nitrogen and some other gases are being trapped while the oxygen is allowed to flow through. The generator produces constant flow of purified oxygen.

Cryogenic air separation processes are routinely used in medium to large scale plants to produce nitrogen, oxygen, and argon as gases and/or liquid products. Cryogenic air separation is the preferred technology for producing very high purity oxygen and nitrogen. It is the most cost effective technology for high production rate plants. All plants producing liquefied industrial gas products utilize cryogenic technology.

PSA Oxygen Molecular Sieve

Zeolite molecular sieve used for PSA oxygen generation is typically sodium X type zeolite. It is a specially produced X type zeolite that has higher dynamic adsorption of nitrogen and N2/O2 separation ratio. With this kind of specially made sodium X, the oxygen production capacity can be greatly increased and can get a oxygen purity as high as 93±3%.

VPSA Oxygen Molecular Sieve

Zeolite molecular sieve used for VPSA oxygen generation is typically lithium based LSX type zeolite. It is much higher performance than the PSA sodium X type zeolite. Since its excellent preformance, it is popularly be used in the VPSA oxygen generation system that is for bigger oxygen generation systems range around from >300 Nm3/hour.

Oxygen Concentrator Molecular Sieve

There are typically two grade zeolite that is widely used in small medical care oxygen concentrator, sodium X type and lithium LSX type. The molecular sieve beads size used in medical oxygen concentrator are very small, normally 0.4-0.8 mm or smaller to increase its performance. The lithium LSX type has much higher performance, which can make the oxygen concentrator much more compact and easier to take around when going outside. While the sodium X zeolite is cheaper and make the oxygen concentrator more economic.

Cryogenic Air Separation Molecular Sieve

The zeolite molecular sieve used in cryogenic air separation is loaded in the pre-purification unit (PPU). The CO2, H2O and other impurities will be removed to a very low level after passing throught the adsorbents (mainly zeolite molecular sieve and activated alumina). The zeolite molecular sieve used in cryogenic air separation including molecular sieve 13X and other high performance new generation of molecular sieves to replace 13X. A Calcium X type 10X are also used in the cryogenic air separation system to remove N2O.
