13XAPG Molecular Sieve

13XAPG Molecular Sieve is a sodium aluminosilicate adsorbent capable of adsorbing molecules with a diameter not exceeding 9 angstroms (A). It effectively removes impurities too large to penetrate Type A crystal pores and is widely utilized for nitrogen-oxygen (N₂/O₂) separation. As the sodium form of Type X crystal, 13XAPG Molecular Sieve features significantly larger pore openings than Type A crystals, along with the highest adsorption capacity among common adsorbents and excellent mass transfer efficiency.

Product Introduction

13X-APG molecular sieve is an alkali metal aluminosilicate featuring a sodium X-type crystal structure. With a pore size of approximately 10Å (angstroms), it exhibits selective adsorption for molecules with a critical diameter of less than 10A. It is widely adopted due to its efficient co-adsorption capability (enabling simultaneous removal of water and carbon dioxide) and superior carbon dioxide selective adsorption performance under specific conditions.

Key Specifications

  • Chemical formula: Na₂O·Al₂O₃·(2.8±0.2)SiO₂·(6–7)H₂O
  • Silicon-aluminum ratio: SiO₂/Al₂O₃ ≈ 2.6–3.0

Applications

  1. Air Separation Unit (ASU-Specific): Deep removal of moisture (H₂O) and carbon dioxide (CO₂) from feed air.
  1. Natural Gas and Liquefied Gas Processing: Drying (moisture removal) and desulfurization (elimination of sulfur-containing impurities such as hydrogen sulfide).
  1. General Gas Deep Drying: Deep drying of various industrial gases (e.g., compressed air, process gases).
  1. Specific Organic Compound Adsorption: Capable of adsorbing molecules with larger critical diameters, including certain aromatic hydrocarbons and branched-chain hydrocarbons.
