CNM 5A molecular sieve has the characteristics of high desulfurization efficiency, large adsorption capacity and regeneration. Through the rich pore structure of the molecular sieve, it can effectively adsorb sulfides and moisture in natural gas, and finally obtain natural gas that meets environmental and industrial quality requirements.

CNM 5A molecular sieve has high selective adsorption, fast adsorption speed, durability and no powdering, and efficient adsorption performance. Through pressure swing adsorption, gases and impurities such as carbon monoxide (CO), methane (CH₄) and nitrogen (N₂) can be removed to produce high-purity hydrogen. It can also adapt to hydrogen pressure swing adsorption devices of various sizes.

Due to its small pore size (about 3Å), 3A molecular sieve mainly adsorbs water molecules, but not larger molecules, so it is widely used in many applications that require precise dehumidification. The following are the main application areas of 3A molecular sieve:

The thermal stability and chemical stability of 4A molecular sieve are relatively high, and its unique selective adsorption characteristics can achieve higher precision drying performance than other adsorbents. In the dryer, when the compressed air mixed with moisture passes through the molecular sieve in the adsorption tower,

Lithium molecular sieve is an oxygen-generating molecular sieve of lithium X-type aluminosilicate crystals, which is used for air separation to produce oxygen and oxygen-enriched air. Compared with ordinary calcium-type and nano-type molecular sieves, it has better adsorption capacity and better separation efficiency. Suitable for small VPSA (vacuum pressure swing adsorption) devices.

The main element of carbon molecular sieve is elemental carbon, and its appearance is a black cylindrical solid. Because it contains a large number of micropores with a diameter of 4 ed, and the micropores have a strong instantaneous affinity for oxygen molecules, it can be used to separate oxygen and nitrogen in the air. Nitrogen is produced by pressure swing adsorption devices in industry.

Insulating glass molecular sieve is a crystalline aluminum silicate mineral spherical particle with a pore size of 3A, which is mainly used for drying the air in the double-layer glass interlayer. Insulating glass molecular sieve can simultaneously absorb moisture and residual organic matter in insulating glass, so that insulating glass can remain smooth and transparent even at very low temperatures. At the same time, it can fully reduce the strong internal and external pressure difference that insulating glass is subjected to due to the huge changes in seasons and day and night temperature differences. Insulating glass molecular sieve also solves the problem of distortion and breakage caused by the expansion or contraction of insulating glass, and prolongs the service life of insulating glass.

Purity and Quality of the Sieves: The effectiveness of molecular sieves in adsorption processes depends heavily on their quality and purity. Customers are concerned with the consistency in quality, the uniformity of bead or pellet size, and the absence of impurities.

Performance Specifications: Customers need to ensure that the molecular sieves meet specific performance criteria, such as adsorption capacity, regeneration capabilities, and the ability to handle specific gas or liquid streams.

Molecular sieves are typically made from materials like zeolites, which are crystalline aluminosilicates. The most common types of molecular sieves are categorized by their pore sizes, measured in angstroms (Å), such as 3A, 4A, 5A, and 13X. Each type is used for different applications depending on the size of the molecules that need to be separated.
