Deep engineering insights into the crystalline aluminosilicate structures that drive selective adsorption processes.
Zeolite 3A, also known as Potassium A (K-A) molecular sieve, is an alkali metal aluminosilicate with a crystalline structure belonging to the LTA (Linde Type A) family. The chemical formula is:
0.4 K₂O · 0.6 Na₂O · Al₂O₃ · 2.0 SiO₂ · 4.5 H₂O
The primary pore window is controlled to approximately 3 Ångstroms (0.3 nm). This critical structural threshold is achieved by substituting sodium ions in the Type 4A framework with larger potassium ions. Because the pore diameter is restricted, Zeolite 3A selectively adsorbs water molecules (kinetic diameter of ~2.65 Å) while excluding larger hydrocarbon molecules, such as ethane, ethylene, propylene, and ethanol. This prevents catalytic reactions, polymerization, and co-adsorption within the framework.
Specially engineered for high mechanical stress in deep beds. Our Zeolite 3A exhibits exceptional crush strength, which prevents dusting, pressure drops, and channel formation in tall industrial drying columns.
Optimized crystal stability allows the material to withstand thousands of adsorption-desorption thermal cycles during Temperature Swing Adsorption (TSA) without losing structural integrity.
Maintains high selectivity for water. This reduces hydrocarbon losses during cracked gas drying and prevents heat generation spikes that could damage the catalyst beds.

Why leading chemical engineers and global buyers source Zeolite 3A from Chinese manufacturers.
Global procurement departments face complex logistics, volatile shipping rates, and stringent quality requirements. To navigate these challenges, companies require reliable manufacturers with deep vertical integration. Shanghai Jiuzhou Chemical coordinates operations across dedicated factories in Shanghai and Wuxi, ensuring consistent product availability even during periods of high demand.
By managing the entire value chain—from sourcing premium raw materials to executing advanced hydrothermal crystallization—we shield our partners from market disruptions. Our logistics division handles container transport, customs documentation, and vacuum packaging to deliver dry, active molecular sieves to ports worldwide.
Our molecular sieves meet strict international standards for petrochemical engineering. We provide comprehensive documentation for municipal and private procurement processes, including raw material certificates (COA), safety data sheets (SDS), and third-party validation reports from SGS and TUV.
Furthermore, our formulations strictly comply with European Union REACH rules, US EPA guidelines, and international customs standards. This seamless regulatory alignment minimizes delivery delays and simplifies importation.

How Zeolite 3A serves as a critical component in high-performance industrial dehydration and gas purification systems.
In ethylene, propylene, and butadiene processing, moisture must be reduced below 1 ppm to prevent freezing in cryogenic separation units.
Jiuzhou’s Zeolite 3A prevents co-adsorption of unsaturated hydrocarbons, minimizing coke formation and extending bed lifetimes.
Breaking the water-ethanol azeotrope (95.6% ethanol) requires selective dehydration to produce fuel-grade anhydrous ethanol (>99.9%).
Our Zeolite 3A excludes ethanol molecules entirely, ensuring clean water adsorption and lower energy consumption during cycle swings.
Moisture trapped inside insulating glass (IG) units leads to fogging, condensation, and chemical corrosion of the spacer system.
Jiuzhou’s low-dusting, high-adsorption molecular sieve beads control dew points down to -70°C for the lifetime of the window.
