5A Molecular Sieve, is an alkaline aluminosilicate. It is a calcium-based synthetic zeolite with an A-type crystal structure. In the production process ion exchange, calcium ions replace sodium ions, making the effective pore size become 5 angstroms (0.5 nanometers). Compared with the 3A/4A molecular sieve desiccant, it can adsorb more acidic gases in the adsorption system.
The strong ionic force of divalent calcium cations makes 5A an excellent choice for removing moisture, carbon dioxide, carbon monoxide, alcohols and other oxygen-containing compounds, hydrogen sulfide, methyl mercaptan and ethyl mercaptan, and other polar molecules.

It is particularly suitable for the adsorption of H2O, CO2, and can also be used for the separation of normal alkanes and isoalkanes (C4 to C6 species) for PSA hydrogen purification and oxygen concentrators.
Xintao provides oxygen-enriched molecular sieve 5A specifically for industrial oxygen production to produce high-concentration oxygen for PSA/VPSA units. Cases can prove that the maximum oxygen concentration can reach 97%.
5A molecular sieve can adsorb molecules with a diameter no greater than 5A. molecules that can be adsorbed by 3A and 4A molecular sieves can also be adsorbed by 5A.
Xintao molecular sieves' annual production capacity of spherical and pellet-shaped molecular sieves can reach tens of thousands of tons, and the safety stock of 5A molecular sieves exceeds 500 tons. As long as you need it, we can ship it quickly, and most importantly, we can ship it to all parts of the world.
Xintao has a complete quality inspection system, providing self-inspection and third-party inspection reports, which can be given to your industry customers for reference. If you need molecular sieve 5A samples, Xintao can also provide them to you free of charge. We have a team with skills and technical knowledge that you can trust to provide support.
Xintao's 5A zeolite is often used in adsorption filtration in petrochemicals, and the oxygen production industry is also guaranteed to have an effect.
Frequently Asked Questions About the 5A Molecular Sieve
5A Molecular Sieve, is an alkali alumina silicate. It is the calcium form of the type A crystal structure. It has an effective pore opening of 5 angstroms(0.5nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger.
5A Molecular Sieve is a type A zeolite with a tetrahedral framework structure, and 13X is an octahedral framework structure of type X zeolite. Their structures are different, and the internal pore sizes formed after ion exchange are different. The internal pore size structure of 5a molecular sieve is 5 angstroms, while the pore size of 13x molecular sieve is 10 angstroms. The range of molecules that can be adsorbed is wider than that of 5a zeolite, and the adsorption capacity is also larger.
If you have ordered a small amount of molecular sieves that have been deactivated and have drying equipment such as a muffle furnace, you can set a high temperature of about 180-250℃ to dry it for about 4-6 hours.
Molecular sieves that have adsorbed acidic gases such as carbon dioxide need to be regenerated at 280-350℃ for about 4-6 hours.
If it is a component-type adsorption regeneration equipment, you only need to set the adsorption and desorption according to the equipment instructions.
Xintao has many export and customer service cases, you can learn about them here.
As a refinery, the customer needs to use molecular sieves to absorb water during the production process of cracking to produce ethylene.
The customer ordered 36 tons of oxygen molecular sieves and 6 tons of activated alumina, and our technical team went to Hunan for on-site installation guidance.
Molecular sieve has a large adsorption capacity, and the general adsorption capacity is 22%
