Rongjian High-Purity Nitrogen Generation Carbon Molecular Sieve (CMS 220-280)

Product Description

Product Description

Carbon Molecular Sieve:

Carbon molecular sieve (CMS) is indeed a crucial material for nitrogen generation via pressure swing adsorption (PSA) technology. Here's a structured overview of its properties and industrial applications based on your description:

1. Composition and Structure
Primary component: Elemental carbon (black columnar solid).
Key feature: Micropores (~4 Å diameter) selectively adsorb oxygen molecules due to their stronger affinity for oxygen over nitrogen, enabling efficient air separation .
2. PSA Nitrogen Production
Mechanism: CMS exploits kinetic selectivity—oxygen diffuses faster into micropores than nitrogen, allowing nitrogen to be collected as the product gas.
Advantages:High nitrogen production capacity and recovery rate.
Long service life, reducing replacement frequency.
Compatibility with various PSA nitrogen generators .
