Aogochem 13X Molecular Sieve stands as the most versatile and widely used large-pore adsorbent in the zeolite family. As a synthetic sodium aluminosilicate with a generous and uniform pore opening of approximately 10 Angstroms (1.0 nm), it possesses the highest adsorption capacity and broadest range of applications among common molecular sieves. Its expansive internal surface area and pore volume enable it to adsorb all molecules captured by smaller-pore sieves (3A, 4A, 5A) and critically, to also adsorb larger, bulkier molecules such as aromatics (e.g., benzene, toluene) and branched-chain hydrocarbons.
This universal adsorption capability makes the 13X Molecular Sieve the cornerstone technology for the simultaneous and deep removal of key gaseous impurities. It excels at eliminating water (H₂O), carbon dioxide (CO₂), and hydrogen sulfide (H₂S) from complex streams in a single step. Engineered by Aogochem for maximum durability, it features exceptional thermal and hydrothermal stability, allowing for repeated regeneration cycles in rigorous industrial environments. Supplied in robust spherical or cylindrical forms, it ensures low attrition, minimal pressure drop, and long, reliable service life in both Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) processes.
For engineering design and procurement evaluation, below are the key specifications for Aogochem's standard 13X Molecular Sieve. We offer customization to meet specific process requirements.

The large-pore structure and high capacity of 13X Molecular Sieve make it a critical component across major global industries, especially in energy and gas processing.
Air Separation & Industrial Gas Production: This is the dominant application. 13X is the standard adsorbent for pre-purification units (PPU) in both cryogenic air separation plants and Pressure/Vacuum Swing Adsorption (PSA/VPSA) systems. It simultaneously removes water and CO₂ from compressed air, protecting downstream equipment from freezing and corrosion, and ensuring the production of high-purity oxygen, nitrogen, and argon for medical, metal fabrication, and chemical uses.
Natural Gas & Refinery Gas Sweetening: Essential for the energy sector, 13X Molecular Sieve performs simultaneous dehydration, desulfurization (H₂S removal), and CO₂ removal from natural gas, associated petroleum gas, and refinery off-gases. This "sweetening" process is crucial for meeting pipeline specifications, preventing equipment corrosion, and preparing feed gas for LNG production.
Petrochemical & Chemical Processing: Its ability to handle larger molecules makes it valuable for drying and purifying a wide range of gas and liquid streams, including cracked gas, aromatics, and specialty solvents. It is also used in separation processes like paraxylene purification and as a catalyst support.
Environmental & Emerging Applications: 13X is a leading candidate for Carbon Capture (CCUS) from flue gases due to its high CO₂ selectivity and capacity. Other uses include landfill gas upgrading, biogas purification, and the drying of insulating gases like SF₆.
Selecting Aogochem guarantees more than a premium adsorbent; it ensures a partnership focused on the reliability and efficiency of your separation processes.
Unmatched Process Reliability: Our 13X Molecular Sieve is manufactured to deliver consistent, high dynamic adsorption capacity and rapid kinetics, which are critical for the efficiency of fast-cycle PSA/VPSA operations. This translates to stable product purity and optimized energy consumption in your plant.
Proven in Critical Applications: We supply industries where failure is not an option, including medical oxygen production and large-scale LNG trains. Our product's proven performance in severe conditions offers peace of mind and reduces operational risk.
Global Technical Expertise: Our support team provides in-depth technical consultation, from assisting with initial adsorbent selection and bed design to optimizing regeneration procedures and troubleshooting, ensuring you achieve the lowest total cost of ownership.
Dedicated Market Support: We tailor our logistics and service to the specific needs of key global markets, including the fast-growing industrial sectors in the Middle East and the demanding environments in Russia and CIS countries, ensuring timely supply and local relevance.
Loading: Ensure towers are clean, dry, and free of oils or contaminants. Use proper loading techniques (e.g., sock loading) to prevent particle segregation and channeling, which can drastically reduce efficiency.
Regeneration: Effective thermal regeneration is key. Follow recommended procedures: purge with a hot, dry gas (typically nitrogen or product gas) at 250-320°C until the bed is thoroughly desorbed. Inadequate heating or cooling can lead to moisture retention and reduced capacity in subsequent cycles.
Storage: The product is hygroscopic. Always keep original packaging sealed until use. Store in a cool, dry, indoor environment on pallets. Reseal any partially used containers tightly.
Safety: While non-toxic and non-flammable, the desiccated material is extremely dry and can cause rapid dehydration on contact with skin or eyes. Always wear appropriate PPE (safety glasses, gloves) when handling. Avoid generating dust. Consult the Safety Data Sheet (SDS) for comprehensive handling and safety information.
