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

CMS-280 is a pelletized carbon molecular sieve intended for oxygen-nitrogen separation in pressure swing adsorption (PSA) nitrogen-generation systems. The listed standard pellet diameters are 1.0-1.3 mm and 1.3-1.5 mm. Custom specifications are also stated as available.

Listed physical specifications include bulk density of at least 660-670 kg/m³, particle strength of at least 85 N, compressive abrasion resistance of no more than 1%, and moisture content of no more than 0.5%. Standard packaging options are listed as 20 kg square buckets, 40 kg round buckets, and 137 kg large drums.

Performance data is provided for operation at 0.7 MPa with an adsorption time of 45-50 seconds and pressure equalization of 1-2 seconds.

Under those stated test conditions, the table reports nitrogen purity and yield combinations of 99% at 320 L/(kg·h), 99.5% at 284 L/(kg·h), 99.9% at 203 L/(kg·h), 99.99% at 137 L/(kg·h), and 99.999% at 100 L/(kg·h). The corresponding listed air-to-nitrogen ratios are 1:2.4, 1:2.9, 1:3.8, 1:5.0, and 1:5.8.

Before procurement, buyers should confirm that the offered batch, pellet size, bulk density, strength, moisture level, and performance test method match the nitrogen generator and operating cycle.

The source information contains additional performance statements made under different conditions, so those values should not be assumed interchangeable with the 0.7 MPa performance table.

Request a batch-specific technical data sheet and test report, and verify the definitions and units used for yield and air-to-nitrogen ratio.

Buyers should also confirm required fill quantity, vessel dimensions, pretreatment requirements, loading procedure, commissioning settings, packaging, and storage conditions before ordering.
