Introduction
5A zeolite powder is an artificially synthesized aluminosilicate crystal powder with an effective pore size of 5 Å, mainly used for separation, purification, and drying of gases and liquids, and is particularly effective in separating normal paraffins from isoparaffins.
advantages
High Purity Crystal Structure: Continuous hydrothermal crystallization ensures a purity of ≥98%, resulting in more stable adsorption performance.
Precise Pore Size: Controlled calcification keeps the pore size accurately at around 5 Å, ensuring more accurate molecular sieving.
Low Moisture Content: Enclosed drying keeps moisture ≤0.3%, reducing moisture absorption and caking.
Uniform Particle Size: Airflow classification maintains D50 at approximately 3.5–4.0 μm, ensuring better dispersion.

Application
Gas Separation: Separation of n-alkanes from iso-alkanes (Dewaxing).
Air Separation: PSA/VPSA Pressure Swing Adsorption, Separation of O2/N2.
Deep Drying: Drying natural gas, liquid hydrocarbons, inert gases, and refrigerants (Anti-freezing).
Purification: Removal of H2S and CO2 from natural gas.
Usage Precautions
Storage: Strictly seal against moisture; otherwise, performance rapidly degrades.
Activation: Must be high-temperature dried (300-400°C) for regeneration before initial use or after moisture exposure.
Safety: Adsorption and activation involve high heat release, use caution against burns.
Maintenance: Regenerate periodically; avoid adsorbing high-boiling-point substances to prevent permanent pore blockage.
Protection: During handling, wear a mask to prevent dust inhalation.
