Bird's nest shaped molecular sieve

Molecular sieve is a type of aluminosilicate compound with a cubic lattice. Molecular sieves have a uniform microporous structure with uniformly sized pores. These pores can adsorb molecules smaller than their diameter into the interior of the pore cavity and have a preferential adsorption ability for polar and unsaturated molecules. Therefore, they can separate molecules with different degrees of polarity, saturation, molecular size, and boiling point, and have the function of "sieving" molecules, hence the name molecular sieve. Due to its high adsorption capacity, strong thermal stability, and other advantages that other adsorbents do not have, molecular sieves have been widely used.

Molecular sieves that have been stored for a long time and have already absorbed moisture should be regenerated before use. Molecular sieves should avoid oil and liquid water. When using, try to avoid contact with oil and liquid water as much as possible. The gases used for drying in industrial production include air, hydrogen, oxygen, nitrogen, argon, etc Connect two adsorption dryers in parallel, one working while the other can be used for regeneration treatment. Alternating between working and regenerating to ensure continuous operation of the equipment.

Honeycomb zeolite molecular sieve is an efficient molecular sieve adsorbent with good adsorption performance, no secondary pollution, and high temperature regeneration. It has been widely used in adsorption, separation, catalysis, and environmental fields, and is suitable for the treatment of high air volume and low concentration organic waste gas.

Zeolite type molecular sieves are usually named after their pore size, such as 3A, 4A, 5A, and 13X. The number represents the diameter of the pore (in angstroms), and the letter represents the type of zeolite. Different types of zeolite molecular sieves have different adsorption properties and selectivity, so they can be optimized for specific applications. Activated carbon molecular sieve is made from carbon materials with high specific surface area, such as charcoal, bamboo charcoal, or coconut shell charcoal. Their pore structure and adsorption performance depend on the raw materials and preparation process. Activated carbon molecular sieves are commonly used for adsorption purification of gases and liquids, as well as for the recovery of organic solvents. Silica molecular sieves are a type of inorganic crystalline material with a tetrahedral structure of silicon and oxygen, such as sodium silicate, potassium silicate, and aluminum silicate. They have high thermal and chemical stability, and are therefore commonly used for adsorption and catalytic applications in high-temperature and corrosive environments.

Bird's nest shaped molecular sieveMolecular sieve is a crystalline material with highly selective pore size, commonly used for adsorption, separation, and catalytic applications. The main characteristic of molecular sieves is their regular pore structure, which allows molecules of specific sizes and shapes to pass through while repelling other molecules. This selectivity enables molecular sieves to play important roles in many industrial processes, such as gas purification, water vapor recovery, and petrochemicals.
