JALON delivers high-performance hydrogen purification molecular sieve solutions for PSA applications—helping industrial operators remove key impurities, protect downstream processes and produce reliable high-purity hydrogen.
High adsorption capacity, rapid adsorption/desorption and high mechanical strength for hydrogen purification applications.
Hydrogen from reforming, refinery and chemical processes commonly contains carbon oxides, nitrogen, methane, moisture and residual hydrocarbons. PSA purification selectively removes these impurities while allowing hydrogen to pass through as product gas.
How PSA hydrogen purification works
H₂ enters the unit with process-specific impurities.
Adsorbent layers selectively retain non-hydrogen components.
Pressure reduction releases impurities for the next cycle.
Multiple beds cycle in sequence for continuous product flow.
PSA is widely applied to hydrogen streams from steam methane reforming, refinery and petrochemical off-gases, coke oven gas, and methanol or ammonia off-gases.
JLWN5 is designed for CO, N₂ and CH₄ removal in an H₂ PSA adsorption bed. For feeds carrying higher moisture, CO₂ or heavy hydrocarbons, it can be combined with appropriate upstream protection layers.
JLWN5 is a synthetic crystalline aluminosilicate with a well-developed three-dimensional pore structure and strong polarity, with a pore opening of 0.5nm. Enabled by a superior formation process, JLWN5 greatly increased the CO, N2, and CH4 adsorption capacity compared with standard molecular sieve 5A.
Designed with the advantages of a large adsorption capacity, fast adsorption & desorption rate and high mechanical strength, JLWN5 is an excellent adsorbent for the PSA hydrogen purification process.
Beyond hydrogen purification, JLWN5 can also be used to separate normal paraffins from branched and cyclic hydrocarbons and for air drying.

| Cycle response | Depends on the selected grade and operating conditions. | Designed for fast adsorption and desorption in cyclic PSA operation. |
| Average crush strength | Approx. 35 N average
Typical: 30–40 N | Typical average crush strength ≥35 N |
| CO adsorption | Approx. 28 ml/g average Typical: 28–30 ml/g | ≥28 ml/g 760 mmHg, 25°C, activated |

JLWN5 is designed for CO removal from hydrogen-rich streams, as well as N₂ and CH₄ adsorption—important separation tasks in hydrogen PSA applications.
Fast adsorption and desorption characteristics help the material respond efficiently as PSA beds alternate between adsorption and regeneration.
High crush strength helps limit bead breakage and dust generation, supporting stable operation in demanding cyclic service.
