Located in Shanghai, the premier economic hub of China, Shanghai Jiuzhou Chemicals Co., Ltd. (JOOZEO) has dedicated nearly three decades to research, development, and manufacturing of high-performance chemical adsorbents. We run dynamic manufacturing processes focusing on quality control and technical innovation.
Our extensive product catalog features premium molecular sieve powders, active zeolites, activated alumina, catalysts, carbon molecular sieves, and silica gels. Every product batch is monitored under rigorous laboratory evaluation to meet demanding international standards. Our manufacturing facilities are ISO9001: 2008, TUV, and SGS certified, guaranteeing consistency and quality control at every phase of production.
Why international enterprises rely on our dual-factory hub in Shanghai & Wuxi.
Positioned adjacent to the world's most active deepwater ports, our Shanghai factory handles high-capacity bulk molecular sieve synthesis, optimizing raw material procurement and reducing international freight lead times. Fully automated control loops ensure constant temperature crystallization and hydrothermal treatment, crucial for homogeneous pore distribution.
Our Wuxi facility focuses on chemical modification, thermal activation at high temperatures (up to 650°C), and dust-free packaging processes. This division of labor optimizes production costs and dynamic capacity scaling, providing our global clients with competitive pricing for bulk supply.
Direct supply networks of raw silicate and aluminum resources from domestic mines minimize chemical precursor costs, passing savings onto our dynamic international clients.
We provide tailored packaging configurations ranging from steel drums (with nitrogen purge protection) and super sacks to customized retail boxes for global distribution.
Located in the Yangtze River Delta cluster, our shipments clear customs swiftly, lowering port processing durations and sea freight costs to primary global ports.

Green manufacturing standard regulating silica desiccant low-carbon production cycles.
Industrial-grade silica and molecular sieves must withstand constant pressure swings and high thermal loads during regeneration cycles. Adhering to standards like HG/T 3927-2007 and JB/T 10532-2017 ensures our products deliver low water dew points (down to -70°C) without particle degradation. Particle attrition leads to powder carry-over, which blocks valves, erodes piping, and reduces the lifespan of downstream process compressors.
Through rigorous QA processes including X-ray Diffraction (XRD) for crystal integrity, nitrogen adsorption isotherms for BET surface area determination, and automated crush testing, JOOZEO produces molecular sieves and silica products that consistently exceed the benchmark guidelines for mechanical resilience and dynamic sorption capacity.
Promoting environmental protection through green manufacturing and high-grade gas purification.
We believe that industrial chemistry must actively protect the environment. JOOZEO enforces green manufacturing systems to limit carbon emissions, capture heat energy, and reuse process water during chemical synthesis.
Seamless procurement channels backed by regional logistics hubs and international compliance standards.
Our adsorbents comply with international chemical frameworks, including EU REACH registration, US FDA DMF filings for food/pharma grade silica applications, and GHS classification directives for safe shipping and handling processes.
We work alongside leading shipping lines and freight forwarders to coordinate dynamic sea, air, and land shipping schedules. Our logistics team provides container temperature monitoring to prevent moisture entry during transport.
We offer engineering support, including vessel volume calculations, dynamic moisture load analysis, pressure drop profiling, and on-site loading supervision to maximize your industrial desiccant lifecycle.
How our molecular sieves and silica products are applied across diverse global supply chains.
In the petrochemical sector, trace moisture in natural gas causes hydrate formation and equipment corrosion under cryogenic separation conditions. Incorporating JOOZEO's 4A and 5A molecular sieves removes water content to below 0.1 ppm, preventing hydrate blockages.
Our specialty alumina silica gels are applied in hydrocarbon dew point control units, showing high resistance to heavy hydrocarbon fouling and thermal shock during regeneration cycles.
Insulating glass units require highly specialized desiccation to prevent internal moisture condensation. Normal desiccants co-adsorb air gases, leading to glass deflection and stress fractures over seasonal temperature variations.
JOOZEO's 3A molecular sieve features a 3-Angstrom pore configuration that selectively adsorbs only water molecules, leaving nitrogen and argon untouched. This preserves structural stability and extends window life.
Anticipating the technological shift in chemical processing and gas purification.
Conventional molecular sieve activation requires high energy input. The industry is moving toward low-carbon activation methods, such as utilizing microwave crystallization and capturing heat exhaust from kilns. At JOOZEO, we are implementing green manufacturing processes that reduce fuel usage in high-temperature operations.
Specialized synthetic zeolites, including modifications of 13X molecular sieves, are becoming essential in post-combustion carbon capture systems. Their high nitrogen-to-carbon dioxide selectivity enables Pressure Swing Adsorption (PSA) units to isolate carbon emissions directly from industrial flue gases.
Blue silica gel utilizes cobalt chloride as a moisture indicator, which faces stricter regulation due to chemical safety concerns. The sector is moving toward orange and yellow indicator gels that rely on safe organic markers, meeting European food and pharma safety requirements.
Integrating IoT-enabled humidity and pressure sensors into adsorption vessels allows real-time monitoring of desiccant beds. This prevents premature replacement, optimizes regeneration times, and reduces operating costs in automated systems.
Direct technical explanations on selecting, handling, and optimizing industrial silica products.
Silica gel is an amorphous form of silicon dioxide featuring an irregular pore structure, making it ideal for general humidity control over a wide relative humidity range. Molecular sieves are crystalline aluminosilicates with uniform pore sizes (3A, 4A, 5A, 13X). They capture water molecules selectively, even at low relative humidity levels, and are commonly used in gas separation and petrochemical applications.
Molecular sieves have a strong affinity for water. Rapid contact with liquid water releases high heat of adsorption, which can cause local thermal stresses, crystal fracturing, and physical attrition. To prevent this, protective beds of silica gel or activated alumina should be installed upstream to handle bulk moisture before the gas stream enters the molecular sieve bed.
Yes, both are regenerable. Molecular sieves are typically regenerated by thermal swing adsorption (TSA) at temperatures between 200°C and 320°C, using a dry sweep gas to carry away desorbed moisture. Silica gels require lower regeneration temperatures, typically between 120°C and 150°C. Exceeding these temperatures can degrade the material's pore structure and reduce its long-term adsorption capacity.
Pore selection depends on the critical diameters of the molecules in the feed gas. A 3A molecular sieve (pore size ~3 Å) adsorbs water while excluding larger molecules like hydrocarbons, preventing co-adsorption. A 4A molecular sieve is standard for drying air and solvents. A 5A molecular sieve adsorbs straight-chain hydrocarbons, making it ideal for paraffin separation, while a 13X molecular sieve (pore size ~10 Å) is used for bulk CO2 and trace hydrocarbon removal from air.
Key indicators include static water adsorption capacity, bulk density, particle crush strength, attrition rate, and packaging integrity. Buyers should review third-party certificates, such as ISO9001, TUV, and SGS, and request a Certificate of Analysis (COA) for each batch to confirm compliance with industrial application requirements.
