High-capacity crystalline metal-aluminosilicates designed for selective molecular dehydration, purification, and separation processes.
Greater Boston is not only an academic and technological epicentre but also a thriving hub for high-tech manufacturing, pharmaceutical synthesis, advanced energy research, and deep-tech aerospace testing. From the biotechnology cluster in East Cambridge to the manufacturing corridors along Route 128, the demand for precise molecular separation and dehydration materials is critical.
Molecular sieves, with their synthetic crystalline aluminosilicate structures, are fundamental in managing trace moisture, purifying process streams, and separating components at the molecular scale. In Massachusetts, local companies encounter demanding environmental regulations and extreme seasonal humidity shifts. The choice of appropriate adsorbents directly impacts the operational reliability of HVAC, cryogenic gas plants, bioprocess containers, and aerospace testing chambers.
Zeolites possess standard crystalline frameworks constructed of silicon-aluminum-oxygen tetrahedra. Substituting cations controls the effective aperture diameter of the pore system. This precise physical control allows molecular sieves to selectively separate molecules based on kinetic diameter differences, steric exclusion, or thermodynamic polarity.
| Zeolite Framework | Cation Species | Effective Pore Size (Å) | Kinetic Cutoff / Adsorbed Species | Primary Boston Applications |
|---|---|---|---|---|
| 3A (LTA) | Potassium (K⁺) | ~ 3.0 Å | H₂O, NH₃ (Excludes C₂H₄, C₂H₆) | Ethanol dehydration, polymer feedstock drying, Insulating Glass |
| 4A (LTA) | Sodium (Na⁺) | ~ 4.0 Å | H₂O, CO₂, SO₂, H₂S, C₂H₄ | Refrigeration systems, closed-loop HVAC, pharmaceutical packaging |
| 5A (LTA) | Calcium (Ca²⁺) | ~ 5.0 Å | Normal hydrocarbons, n-butane (Excludes branched molecules) | PSA hydrogen purification, paraffin separation, fuel cell pretreatment |
| 13X (FAU) | Sodium (Na⁺) | ~ 9.0 Å | Heavy organic complexes, mercaptans, aromatic hydrocarbon groups | Cryogenic air pre-purification (CO₂ & H₂O extraction), medical concentrators |
| CMS (Carbon) | Amorphous Carbon Matrix | ~ 3.0 - 5.0 Å | O₂ (adsorbs faster than N₂ due to kinetic rate differential) | PSA nitrogen generators for laboratories, electronics assembly |

Over 30 years of excellence in R&D, chemical synthesis, and global adsorbent distribution networks.
Shanghai Jiuzhou Chemicals Co., Ltd., operating globally under the brand JOOZEO, is situated in Shanghai, one of the most prominent manufacturing and economic hubs in China. Throughout our history, we have remained committed to the operational core of "quality control, constant innovation." This focus guides the development, research, and fabrication of advanced chemical products, including molecular sieve powders, active alumina, silica gel catalysts, ceramic packing elements, and specialized zeolite catalysts. Our production system is certified under ISO 9001:2008, TUV, and SGS frameworks.
With advanced technical capabilities and laboratories configured with modern monitoring instruments, JOOZEO produces high-stability desiccants and adsorbents. We maintain comprehensive manufacturing sites in both Shanghai and Wuxi, allowing us to manage large production capacities while meeting international chemical and physical standards. Our product catalog is exported worldwide, supported by global distribution networks and warehousing infrastructure designed to ensure seamless delivery to customers in the Americas, Europe, the Middle East, and Asia.
Our operational presence consists of specialized manufacturing units in Shanghai and Wuxi, designed to deliver high levels of consistency. We utilize automated calcining systems, precise granulators, and dust-free packaging configurations to ensure our materials maintain high adsorption capacity and crush strength.
Quality control is integrated throughout our manufacturing process. Every batch is evaluated in our dynamic lab environments to assess adsorption rates, thermal stability, bulk density, attrition rates, and crushing limits. We aim to supply materials that consistently meet or exceed international standards.
JOOZEO contributes to establishing and refining industrial standards for compressed air dryers and activated alumina.
Adsorption compressed air dryers for general use.
Activated aluminium oxide for industrial use.
Refrigeration compressed air dryers for general use.
High-efficiency gas separation and dryer norms.

"Better air, Better life" — A commitment to low-emission chemical manufacturing.
Our corporate responsibility program includes investments in environmental systems across our manufacturing plants. Synthesizing zeolites requires thermal processing and water usage. Through our water recycling systems and high-efficiency gas-fired calcining kilns, we work to reduce the carbon footprint of our operations.
For our partners in Boston and throughout the United States, our focus on carbon emission reductions aligns with local and regional corporate sustainability targets. Additionally, our carbon molecular sieves support nitrogen production systems, replacing high-emission transportation processes with on-site gas separation.
