5A Molecular Sieve Desiccants
5A molecular sieve desiccants offers efficient gas separation, purification, and dehydration solutions across petrochemical, energy, and environmental industries.
  • Diesel Dewaxing: Adsorbs normal paraffins (e.g., wax) to improve diesel’s low-temperature fluidity. (Example: Sinopec Jinling Branch’s dewaxing project using 5A molecular sieve desiccants).
  • Natural Gas Purification: Removes acidic gases like H₂S and CO₂ to enhance gas purity.
  • Isomer Separation: Separates normal paraffins from isoparaffins to optimize gasoline octane ratings.

Gas Separation & Purification

  • Pressure Swing Adsorption (PSA) for Oxygen/Nitrogen Generation: Selectively adsorbs N₂, enriching oxygen concentration to over 90%.
  • Hydrogen Purification: Removes CO, CO₂, and other impurities to achieve high-purity hydrogen.
  • Air Purification: Adsorbs moisture and CO₂ in air separation pre-treatment systems.

Chemical & Industrial Drying

  • Organic Solvent Dehydration: Dehydrates solvents like ethanol and acetone to prevent degradation.
  • Refrigerant Drying: Prevents ice blockages and acidic corrosion in refrigerant systems (e.g., R22).

Environmental Protection & Waste Gas Treatment

  • Industrial Flue Gas Desulfurization (SO₂ Removal): Adsorbs acidic gases to reduce air pollution.
  • VOC (Volatile Organic Compounds) Adsorption: Applied in chemical exhaust gas treatment.

Other Specialized Applications

  • Food Packaging Desiccants: Prevents moisture damage and spoilage.
  • Electronics Moisture Protection: Shields sensitive electronic components from humidity.

With high adsorption capacity, strong regeneration ability (regenerates via 200-350℃ heating), and excellent mechanical strength (attrition rate ≤0.3%), 5A molecular sieve desiccants continues to play a vital role in energy, environmental, and chemical industries.
