High Grade Molecular Sieves

By keeping track with the market developments, we are eminent Manufacturer & Exporter of High Grade Molecular Sieves in Pingxiang, Jiangxi, China.

1. Molecular Sieve 3A
Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an aperture about 3 angstroms (0.3nm). It doesn't absorb any molecules larger than 3A. Ita s used for absorbing water mainly. Yuanying Molecular Sieve 3A has quick absorption speed, high crushing resistance and pollution resistance, more regenerative times and long lifespan. Ita s the best desiccants for the deep desiccation, refining and polymerization of the gaseous phase and liquid phase in the petrochemical industry.
Typical Chemical Formula: 2/3K2O-1/3Na2O-Al2O3-2SiO2-9/2H2O
2. Molecular Sieve 4A
Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an aperture about 4 angstroms (0.4nm). It doesn't absorb any molecules larger than 4A, including propane. It absorbs water, methanol, ethanol, sulfureted hydrogen, sulfur dioxide, carbon dioxide, ethylene, propylene mainly.
Typical Chemical Formula: Na2O-Al2O3-2SiO2-9/2H2O
3. Molecular Sieve 5A
Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an aperture about 5 angstroms (0.5 nm). It absorbs any molecules less than 5A. It is especially used in separation of the normal and isomerous alkane, Pressure Swing Absorption for gas, co-absorption of moisture and carbon dioxide. It is widely applied in different kinds gas PSA equipment.
Typical Chemical Formula: 3/4CaO-1/4Na2O-Al2O3-2SiO2-9/2H2O
4. 5A Oxygen-enriched
Type 5A small oxygen enrichment molecular sieve is a kind of appropriative molecular sieve specially designed for medical or healthy oxygen generator--a mini PSA plant for medical application. The product has the feature of high purity of oxygen concentrating and long lifespan. It is already widely used in the medical care field.
Typical Chemical Formula: 4/5CaO-1/5Na2O-Al2O3-2SiO2
5. Molecular Sieve 13X
Molecular Sieve 13X is the sodium form of the type X crystal and has an aperture than the type A crystals. It absorbs any molecules less than 10A, mainly used as catalyst carrier, co-absorption of CO2 and H2O, co-absorption of H2O and H2S. It is used as desiccants for medical and air compressor.
Typical Chemical Formula: Na2O-Al2O3-2.5SiO2-nH2O
6. Molecular Sieve Power
The original powder of molecular sieve produced in our company is artificial white powder of zeolite, having the effective performances of adsorption and selectivity. According to its crystal structure and chemical composition, is divided into type A, type x and type Y.
7. Carbon Molecular Sieve
Carbon molecular sieve is a new kind of adsorbent developing from 1970, and is excellent non-pole carbon material. It can be used as separate the nitrogen from the oxygen under normal temperature and pressure. To compare with tradition, PSA has some advantages: the investment is lower, start-up time is short, and the cost for nitrogen is lower. It has been widely applied in petroleum chemical industry, metal heat treatment, electron production and keep-fresh of foodstuff.
