Explore our top-tier specialized molecular sieves and active zeolite powders manufactured to strict international quality standards.
Shanghai Jiuzhou Chemicals Co., Ltd. is strategically established in Shanghai, the premier economic hub of China. For nearly three decades, Jiuzhou has consistently adhered to the core philosophies of rigorous quality control and technical innovation. Our dedication centers on developing, manufacturing, and distributing high-end chemical adsorbents globally.
Our expansive portfolio includes premium active molecular sieve powders, synthetic molecular sieves, activated alumina, catalysts, ceramic tower packings, sodium silicates, and specialty zeolites. Backed by ISO9001:2008, TUV, and SGS certifications, we ensure every bulk shipment satisfies the uncompromising demands of our international clientele.
Streamlined global supply chain structures tailored to complex commercial requirements, large-scale industrial drying systems, and volume pricing dynamics.
We provide bulk packaging configurations including 500kg/1000kg super sacks, heavy-duty airtight steel drums, and customized moisture-barrier packaging. Sieve sizing and particle distributions can be tuned to reduce flow resistance in process plants.
Utilizing our strategic location in coastal China, we coordinate rapid transit pipelines through Shanghai and Ningbo ports. Full container load (FCL) transport ensures cargo integrity and prevents atmospheric humidity degradation during ocean transit.
Every industrial batch ships with verified Certificates of Analysis (COA). Our manufacturing operations conform strictly to environmental assessments, hazardous material compliance protocols, REACH specifications, and local safety rules.

Take a look inside our state-of-the-art facilities in Shanghai and Wuxi. Operating automated production lines and comprehensive quality laboratories.
Our Shanghai base coordinates strategic raw material processing, quality checks, and international customer service. It functions as the logistical nucleus for our global distribution chain.
Equipped with advanced rotary kilns, spray dryers, and high-capacity pelletizers, the Wuxi plant manages large-scale, continuous manufacturing of molecular sieve beads, powders, and extruded pellets.
How synthetic crystalline aluminosilicates are engineered to address critical separation and purification challenges across various global sectors.
Modern ASUs require extreme feed gas purity to prevent heat exchanger freezing. Our engineered 13X zeolite adsorbents selectively strip trace moisture, carbon dioxide (CO₂), and light hydrocarbons from incoming air before it reaches the sub-zero distillation column.
To produce clean, engine-grade anhydrous ethanol, water must be broken past the azeotropic barrier. Utilizing a high-purity Zeolite 3A molecular sieve bed, water molecules are systematically trapped inside the crystalline cavities while ethanol passes cleanly through.
In refining plants, cracked gas streams and natural gas lines must remain bone-dry to prevent hydrate blockages and pipeline corrosion. Our high-durability spherical molecular sieves offer deep dehydration down to less than 0.1 ppmv water content.
Trace moisture in paints, coatings, and polyurethane resins causes foaming, pinholes, and reduced curing stability. Our ultra-fine activated zeolite powders act as efficient internal moisture scavengers, ensuring smooth coatings and uniform polymer density.
Our custom zeolites and carbon molecular sieves are optimized for selective gas capture, including volatile organic compound (VOC) adsorption, greenhouse gas capture, and the removal of hazardous sulfur compounds (H2S, mercaptans).
With an engineered lithium-exchanged framework, our oxygen-generation sieves showcase a high nitrogen-to-oxygen separation factor, enabling medical facilities and industrial plants to run compact, high-output oxygen generators.

We believe in manufacturing cleaner materials to foster a greener global environment, lower industrial energy use, and promote circular economies.
Our engineering roadmaps target cleaner production paths and higher-capacity frameworks to meet evolving industrial requirements.
By optimizing crystallization kinetics, our research team is moving away from organic structural directing agents (templates). This method significantly reduces VOC emissions during calcination and lowers the primary carbon footprint of bulk synthetic zeolite production.
Under demanding process conditions, thermal stability and acid resistance are key to prolonged lifetime. We are working on high-silica MFI and CHA framework zeolites designed for gas separation and environmental remediation in challenging chemical streams.
Regenerating desiccants requires substantial energy inputs. We are developing modified zeolite pore surfaces that reduce water-adsorbent affinity at high temperatures, lowering the activation energy needed for desorption cycles.
Deep technical answers straight from our laboratory engineers, helping you make informed bulk procurement decisions.
The performance of bulk synthetic zeolite is determined by crystalline purity, specific surface area (verified via BET measurement), pore size distribution, static water adsorption capacity, and mass loss on ignition (LOI). Our manufacturing operations utilize inline X-ray diffraction (XRD) tests to verify optimal crystallization and avoid non-adsorptive amorphous phases.
Zeolite 3A features a nominal pore opening of roughly 3 Å. Water molecules (diameter ~2.6 Å) easily pass into the internal pores for adsorption, while ethanol molecules (diameter ~4.4 Å) are excluded due to steric hindrance. This prevents co-adsorption and avoids catalyzed ethanol side-reactions.
For bulk ocean freight, we package zeolites and molecular sieves in air-tight plastic-lined woven bags (super sacks) or steel drums sealed with heavy elastomeric gaskets. We monitor humidity levels in our warehouses and during loading to prevent pre-activation before delivery.
Yes, synthetic zeolites can be regenerated via temperature swing adsorption (TSA) or pressure swing adsorption (PSA). Thermal regeneration typically requires heating the material to 200°C–350°C under a dry purge gas stream. Sustaining temperatures above 550°C for extended periods should be avoided, as this can degrade the aluminosilicate crystal framework.
