Engineered for high mass transfer, optimal mechanical strength, and outstanding chemical durability.
Established as a central pillar of technological innovation and quality leadership, Shanghai Jiuzhou Chemicals (JOOZEO) operates from the dynamic economic heart of Shanghai. With a primary focus on dynamic adsorption mechanisms, catalyst substrates, and synthetic zeolite structures, we have spent decades refining our core competencies.
We synthesize a comprehensive family of molecular sieves, including 3A, 4A, 5A, 13X, and specialized oxygen generator variants (Li-LSX, Ca-A). Through rigorous implementation of advanced material sciences, we supply high-performance molecular sieve powders, activated powder matrices, activated alumina, catalysts, sodium silicates, aluminum hydroxides, and premium ceramic packaging media.
All process divisions operate under full accreditation conforming to ISO9001:2008 standards alongside extensive third-party qualifications verified by TUV and SGS laboratories. When engineering components for natural gas purification, medical-grade oxygen production, or petrochemical cracked-gas separation, our material parameters deliver long life cycle stability and precise selectivity.
Unlocking thermodynamic and kinetic selectivity through precisely-engineered crystalline aluminosilicate structures.
Molecular sieves utilize uniform crystalline pore networks to filter molecules based on spatial geometry (size exclusion) and electrostatic affinity. Synthesized from alkaline metal aluminosilicates, these zeolites display a three-dimensional framework constructed from AlO4 and SiO4 tetrahedra. The structural charge imbalances are compensated by cations (Na+, K+, Ca2+, Li+), which create intense local electrostatic fields inside the cage structure.
These ionic fields polarize incoming compounds, facilitating the selective capture of polar species (such as H2O, H2S, NH3, and CO2) while allowing non-polar gases of comparable kinetic diameters to pass unhindered. Controlling the cation type determines the pore opening: 3A (potassium-substituted), 4A (sodium-form), 5A (calcium-substituted), and 13X (faujasite-type with ~10Å pore openings). Custom adjustment of these configurations is vital for demanding industrial purification processes.
As industrial demands transition toward lower carbon outputs and higher energy conservation, the development of synthetic zeolites focuses on reducing thermal regeneration penalties and increasing hydrothermal durability. Joozeo's R&D path emphasizes:
Every single batch undergoes meticulous characterization. We verify key properties including XRD crystalline phase purity, BET surface area, bulk density, crushing strength, and water adsorption capacity. This ensures zero channel-bypass and long bed lifespans inside industrial vessels.
Innovation is embedded in our engineering culture. Working alongside academic research institutes, our R&D center continuously refines catalyst carrier structures and designs tailored desiccants for challenging trace contaminants in feed streams.
Combining two state-of-the-art facilities to guarantee continuous production, cost efficiencies, and reliable global delivery.
Our Shanghai manufacturing plant leverages high-level automation to run continuous synthesis, extrusion, and calcination lines. This facility specializes in high-precision activated alumina formulations and customized molecular sieve spheres tailored for demanding petrochemical applications.
The Wuxi factory acts as an essential production node for bulk synthetic zeolite powders, sodium silicates, and ceramic structural packing. Operating alongside Shanghai, it ensures a highly resilient supply chain that mitigates raw material delays and meets seasonal logistics requirements.
Dual production locations safeguard client supply agreements against regional power, environmental, or transport variations.
Equipped with high-resolution gas chromatographs, dynamic breakthrough test rigs, and automated physical property analyzers.
Fast, direct connections to major deepwater ports in Shanghai ensure efficient shipping and reliable delivery schedules globally.
Engineered to deliver reliable, efficient molecular separation across multiple key industrial sectors.
Preventing downstream equipment freezing and poisoning by utilizing 3A molecular sieves for cracked gas drying. This allows deep dehydration down to less than 1 ppm moisture content without co-adsorbing ethylene.
Extracting trace carbon dioxide, hydrogen sulfide, and mercaptans in gas processing plants using specialized 4A, 5A, and 13X matrices prior to liquefaction (LNG) processes.
Utilizing high-capacity 13X APG molecular sieves within pre-purification units (PPU) to clean input air. Eliminating moisture and CO2 avoids column plugging in cryogenic processing.
