At a Glance: Shanli Molecular Sieve Model Selection Guide

May 29, 2026

In PSA nitrogen generation, oxygen production, and air drying, selecting the right molecular sieve directly impacts gas purity, energy consumption, service life, and system stability. Incorrect selection can lead to substandard output, high energy use, and powdering or clogging of the sieve. Shanli molecular sieves cover a wide range, including carbon molecular sieves for nitrogen generation, oxygen generation, methane purification, noble gas enrichment, and general adsorbents, suitable for small, medium, and large industrial systems. This guide includes a selection table to help you quickly match Shanli sieve models to your application needs. For detailed parameters or custom solutions, please contact us.

1.Core Product Categories

Based on application and adsorption principle, Shanli molecular sieves fall into three main categories:

Nitrogen-Generation Molecular Sieves，for nitrogen enrichment and separation

Oxygen-Generation & Methane-Purification Sieves，for efficient gas enrichment

Multifunctional Adsorbents (3A, 4A, 5A)，selectively adsorb water, CO₂, and other impurities based on pore size, ideal for gas drying and purification

2.Model Selection Table

Selection logic: Define application & gas requirement → verify purity & output performance → match physical parameters & system scale. The table below provides a quick selection guide. For detailed parameter interpretation or custom matching, please contact us.

Model	Type	Key Performance (N₂ efficiency at 0.7MPa)	Typical Applications
SLCMS-UEP	N₂-dedicated CMS	• 99.99% → 175 Nm³/h·t • 99.9% → 250 Nm³/h·t • 99.5% → 340 Nm³/h·t	Ultra-high purity N₂, e.g., electronics, pharmaceutical packaging, chemical blanketing. Suitable for PSA systems requiring stable 99.999% N₂.
SLUHP-100	N₂-dedicated CMS	• 99.99% → 148 Nm³/h·t • 99.9% → 210 Nm³/h·t • 99.5% → 310 Nm³/h·t	Ultra-high purity N₂ with energy savings, e.g., electronics manufacturing, pharma production.
SLCMS-HP1	N₂-dedicated CMS	• 99.99% → 125 Nm³/h·t • 99.9% → 185 Nm³/h·t • 99.5% → 275 Nm³/h·t	High N₂ recovery, e.g., food packaging, coal mine fire prevention, chemical blanketing. Reduces compressed air consumption.
SLCMS-G1.3	N₂-dedicated CMS	• 99.99% → 120 Nm³/h·t • 99.9% → 175 Nm³/h·t • 99.5% → 265 Nm³/h·t	High mechanical strength or large medium/low-purity N₂ demand, e.g., mine fire prevention, oil tank blanketing, grain storage, ship inerting. Coarse particles reduce pressure loss.

Model	Type	Key Performance	Typical Applications
SLCMS-OG	Oxygen enrichment adsorbent	High O₂ concentration & recovery; up to 99.5%+ O₂	PSA oxygen generation, e.g., medical oxygen, plateau oxygen supply, oxygen-enriched combustion.
SLCMS-CBG	Methane purification CMS	Adsorbs N₂, CO₂, etc. from methane to increase purity & recovery	Coalbed methane / biogas / natural gas purification to improve heating value and pipeline gas standards.
3A	General adsorbent	Selectively adsorbs water; excludes molecules >0.3nm (e.g., ethylene, propane)	Desiccant for insulating glass, drying unsaturated hydrocarbon streams (e.g., cracked gas).
4A	General adsorbent	Adsorbs water, methanol, ethanol, etc.; excludes branched alkanes	Deep drying of air, natural gas, refrigerants; static dehydration.
5A	General adsorbent	Separates normal from iso-alkanes; adsorbs straight-chain molecules <C5	Pre-treatment for high-purity N₂ by PSA; separation of CO₂, H₂ from industrial gases.
