13X Molecular Sieve Product advantages

Possesses outstanding adsorption performance for water vapor, carbon dioxide and trace organic impurities, which can effectively purify various industrial gases and achieve deep dehydration and decarbonization treatment.

Adopts well-molded spherical particles with low abrasion rate, producing little dust during long-cycle adsorption and regeneration, effectively protecting downstream pipeline and equipment.

Features excellent thermal stability and reliable regeneration performance. It can realize repeated adsorption-desorption cycles under standard operating conditions, greatly reducing overall material replacement costs.

Comes with uniform particle size and stable bulk density, maintaining balanced airflow distribution inside adsorption towers and avoiding excessive pressure drop to guarantee continuous and stable system operation.

Boasts extensive application compatibility, perfectly matching working conditions of air separation units, natural gas purification, petrochemical gas processing and compressed air drying systems.

13X Molecular Sieve Product Introduction

13X Molecular Sieve is a kind of sodium-type crystalline aluminosilicate zeolite with uniform pore size of 10Å. It features strong selective adsorption capacity and can adsorb molecules whose critical diameter is less than 10 angstroms. Compared with other common zeolite adsorbents, 13X molecular sieve is capable of simultaneously removing water vapor, carbon dioxide and some light hydrocarbons from gas streams, which cannot be achieved by single-function desiccants.

Our spherical 13X molecular sieve is manufactured via advanced molding and high-temperature activation technology. The product has uniform particle size, high mechanical strength, low abrasion rate and stable adsorption performance. It can withstand repeated adsorption and thermal regeneration cycles without obvious performance attenuation.

Widely adopted in industrial gas treatment fields including air separation units, compressed air drying, natural gas purification, petrochemical gas dehydration and LPG purification. It effectively eliminates H₂O and CO₂ to prevent freezing and blocking of pipelines and equipment, ensuring safe and continuous operation of downstream production systems. Customized particle sizes such as 1.6–2.5mm, 3–5mm are available to meet different design requirements of adsorption towers.
