High purity molecular sieve

In PSA nitrogen generation, oxygen production, and air drying, the right molecular sieve ensures gas purity, energy efficiency, longevity, and stability. Shanli offers carbon molecular sieves for nitrogen, oxygen, methane, noble gas enrichment, and general adsorption. This selection table helps you quickly find the right Shanli model. For detailed specs or custom solutions, 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.
