13X APG molecular sieve is a molecular sieve with a nano-X crystal structure. It is composed of aluminosilicate and has a pore size of 10A. It is to meet the special requirements of the cryogenic air separation industry. A special molecular sieve produced to further improve the adsorption capacity of molecular sieves for carbon dioxide and water and avoid the freezing tower phenomenon during air separation.

13X-HP molecular sieve is a new type of X-type molecular sieve specially used for oxygen production. The principle of oxygen production is: through the pressure swing adsorption of air through the compressor, the air is extracted into the 13X-HP molecular sieve. The molecular sieve absorbs nitrogen, carbon dioxide and other waste in the air, and only the remaining oxygen enters the gas collection bottle and is purified under high pressure through the high-pressure valve. , the oxygen generator can output oxygen after raising the concentration to the standard.

CNM 3A molecular sieve, suitable for drying gases and liquids and dehydrating hydrocarbons. It is widely used in deep drying of petroleum cracked gas; cracked gas generally contains a lot of water, which will form ice during cryogenic separation operations, and can cause blockage of pipelines and equipment with hydrocarbon hydrate crystals. Because petroleum cracked gas must undergo deep dehydration before cryogenic separation, the moisture content in the cracked gas is reduced. Since the 3A molecular sieve only adsorbs water in the cracked gas and does not adsorb larger hydrocarbon molecules,

CNM 3A molecular sieve has the characteristics of uniform pore size/21% static water adsorption value/fast adsorption speed/high strength and not easy to break/selective adsorption of moisture. It can effectively dry gas in high and low temperature environments and is commonly used for compressed natural gas. Highly efficient dehydration adsorbent.

CNM 4A molecular sieve is widely used in industrial ethanol production and drying, such as ethanol distillation and pressure swing adsorption ethanol purification. CNM molecular sieve has high strength and high adsorption performance, which can effectively remove water molecules in ethanol, thus improving the purity of ethanol. It is widely used in the fields of chemicals, food industry, and cosmetics.

NM 3A molecular sieve has excellent adsorption performance and chemical stability, and can effectively remove moisture from methanol compounds. It can be used to produce methanol from natural gas, produce acetic acid, fuel, leather processing, cleaning and degreasing agents, produce formaldehyde, produce olefins, agricultural organic fertilizers, etc. fields are widely used.

NM 3A molecular sieve has extremely high affinity for moisture and can selectively adsorb water molecules. In the acetylene drying device, the acetylene passes through a drying tower equipped with a powder sieve, and the moisture in the acetylene is adsorbed onto the molecular sieve through physical adsorption, thereby achieving acetylene drying.

CNM 3A molecular sieve has the advantages of uniform pore size, large specific surface area, intact particles without fragmentation, long service life, stable quality, extremely high affinity for water, and can selectively adsorb water molecules. The moisture in isopropyl alcohol can be adsorbed onto the molecular sieve to achieve drying of isopropyl alcohol.

CNM 3A molecular sieve is widely used in the dehydration of chlorobenzene solvents. It has a specific pore size and can selectively adsorb molecules. When molecular sieve is added to chlorobenzene, 3A molecular sieve will adsorb water molecules in chlorobenzene, thereby reducing the water content in chlorobenzene. It has good water removal effect and is easy to operate. It is suitable for small and medium-sized water removal needs.
