13x molecular sieve desiccants
13X molecular sieve desiccants ensures efficient gas drying, purification, and VOC removal with high adsorption, regenerability, and mechanical strength.

13X molecular sieve desiccants (pore size ~10Å) is widely used across industries due to its large pore structure and strong adsorption capacity. Below are its main applications and technical details:

Gas Drying and Purification

  • Air Separation Units (ASU): Removes H₂O and CO₂ before cryogenic air separation to prevent freezing and equipment blockages.

  • Industrial Gas Drying: Applied in compressed air, nitrogen, hydrogen drying to ensure high gas purity.

  • Natural Gas & LPG Dehydration: Lowers dew point to prevent pipeline corrosion and hydrate formation.

Chemical & Petrochemical Industry

  • Liquid Hydrocarbon Desulfurization: Adsorbs H₂S and mercaptans to improve fuel quality.

  • Catalyst Carrier: Used in petroleum cracking and hydrogenation to enhance catalytic efficiency.

  • Solvent Recovery: Captures VOCs like benzene and toluene, reducing emissions.

Environmental Protection & Waste Gas Treatment

  • Industrial Waste Gas Purification: Removes acidic gases such as SO₂ and CO₂ to meet emission standards.

  • Papermaking Wastewater Treatment: Composite sieves effectively remove color, suspended solids, and COD.

Pharmaceutical & Electronics Industry

  • High-Purity Solvent Dehydration: Ensures solvent purity (ethanol, isopropanol) for synthesis and electronic cleaning.

  • Moisture Protection for Electronics: Prevents moisture damage in precision components.

Other Specialized Applications

  • Oxygen Enrichment: In PSA oxygen generation, selectively adsorbs N₂ to produce high-purity O₂.

  • Food Packaging Desiccant: Prevents moisture-induced spoilage in food products.

With high adsorption capacity (static water adsorption ≥25%), excellent regenerability (thermal desorption at 200-350°C), and superior mechanical strength (attrition rate ≤0.2%), 13X molecular sieve remains essential in energy, chemical, and environmental industries.
