The 5A Molecular Sieve is an alkali earth metal aluminosilicate, specifically the calcium form of the Type A crystal structure. With an effective pore opening of exactly 5 angstroms (0.5 nm), it is engineered to adsorb molecules with a kinetic diameter smaller than 0.5 nm while excluding larger ones. This highly selective property makes it the premier adsorbent for separating normal paraffins from branched and cyclic hydrocarbons, as well as for various Pressure Swing Adsorption (PSA) purification processes.
Accurately separates normal paraffins from branched-chain and cyclic hydrocarbons, significantly improving fuel octane ratings and chemical purity.
Delivers high dynamic and static adsorption rates for water, carbon dioxide, and hydrogen sulfide, ensuring deep purification.
Manufactured through advanced extrusion and rolling processes, ensuring massive crushing strength to withstand high-pressure deep desiccant beds without powdering.
Perfectly optimized for Pressure Swing Adsorption (PSA) technology, providing reliable and continuous high-purity hydrogen generation and oxygen concentration.
Features phenomenal thermal and hydrothermal stability, allowing for repeated regeneration cycles at high temperatures without losing critical adsorption efficiency.

A 5A molecular sieve has an effective pore opening of 5 angstroms (0.5 nm), allowing it to selectively adsorb molecules smaller than 0.5 nm while completely excluding larger molecules.
It delivers high adsorption capacity for moisture, carbon dioxide (CO2), hydrogen sulfide (H2S), normal paraffins, and other polar or moderately sized molecules under 5 angstroms.
It is specially optimized for Pressure Swing Adsorption (PSA) technology, providing superior dynamic capacity and rapid mass transfer for hydrogen purification and oxygen concentration systems.
Yes. Due to its superior thermal and hydrothermal stability, it can undergo repeated thermal or pressure regeneration cycles without significant loss of adsorption capacity or structural integrity.
The product is available in spherical beads (1.5-2.5mm and 3.0-5.0mm) and cylindrical extruded pellets (1.6mm / 1/16" and 3.2mm / 1/8") to match diverse tower designs and pressure drop requirements.
