Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Molecular Sieves. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This 4A molecular sieve is an alkali aluminosilicate in the sodium form of the Type A crystal structure. Its nominal pore opening is 4 angstroms (0.4 nm), allowing it to adsorb many molecules with kinetic diameters below 4 angstroms while excluding larger molecules.
The stated applications include drying and carbon dioxide removal from natural gas, LPG, air, inert gases, and atmospheric gases. It may also be used to remove hydrocarbons, ammonia, and methanol from gas streams. Available forms include spheres and pellets.
Sphere diameters are listed as 1.7–2.5 mm and 3.0–5.0 mm, while pellet diameters are listed as 1.6 mm and 3.2 mm. Across the listed grades, static water adsorption is at least 22%, static methanol adsorption is at least 15%, water content is no more than 1.0%, and wear ratio is no more than 0.20%.
Bulk density, crushing strength, and size conformity vary by form and diameter. The material can be regenerated through heating in thermal-swing processes or by lowering pressure in pressure-swing processes.
It should be protected from moisture and organic pre-adsorption before operation;material exposed during storage or handling may require reactivation.
Procurement confirmation: Before ordering, buyers should confirm the required particle form and size, operating gas composition, inlet moisture and contaminants, target outlet specification, pressure and temperature cycle, regeneration method, and expected service conditions.
Buyers should also request the grade-specific test method, inspection documentation, packaging configuration, and batch acceptance criteria. Dew-point performance should be confirmed for the actual process because outlet results depend on gas composition and operating conditions.
