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 zeolite molecular sieve is a spherical mineral desiccant and sorbent with the listed formula Na₂O·Al₂O₃·2. SiO₂·4.5H₂O. It is intended for adsorption of water, methanol, ethanol, and similar listed substances.
The described high-strength configuration is presented for compressed-air drying, high-flow systems subject to pressure changes, and regeneration of desulfurization agents in petrochemical or refinery processes.
For this configuration, the stated performance includes static water adsorption of at least 22%, crush strength of at least 140 N per bead, bulk density of 0.75–0.78 g/ml, and attrition of no more than 0.2%. Its listed particle range is 2.5–5 mm, with 3.2–4.8 mm identified as typical.
The source information also lists other selectable particle ranges: 0.4–0.8 mm, 1–2 mm, 1.6–2.5 mm, and 2–4 mm. These may represent different configurations with different performance values.
Another general specification set states bulk density above 0.69 g/ml, compressive strength above 8 N, static water adsorption above 21.5% by weight, wear below 0.2% by weight, and water content below 1.5% by weight.
Procurement note: buyers should not assume that the high-strength figures apply to every offered particle size. Before ordering, confirm the exact grade, bead-size distribution, test method, minimum strength, adsorption capacity, supplied moisture content, and attrition limit on the quotation and inspection document.
The listed methanol adsorption value of less than 140 mg/g should also be clarified because the direction of that limit may not express a minimum adsorption requirement. The listed net weight is 25 kg, while packaging information mentions double-layer inner-film woven bags and carton packing.
Storage is specified as a ventilated, dry room. Buyers should confirm the packaging format and net weight for the selected grade, as separate shipment data lists a 50 kg gross package weight.
