Explore our core engineering catalog, designed for extreme durability, ultra-low dew points, and reliable molecular separation.
Located in the premier economic development hub of Shanghai, Shanghai Jiuzhou Chemicals Co., Ltd. (JOOZEO) has consistently adhered to the foundational principles of strict quality control and perpetual technological innovation. Over the decades, we have committed ourselves to the research, development, and high-precision manufacturing of molecular sieves and advanced adsorbents.
Our core capabilities include the fabrication of raw zeolite powders, molecular sieve beads/pellets, activated molecular sieve powder, activated alumina, industrial catalysts, and specialized packing materials. Certified under the ISO9001: 2008 system, and fully audited by TUV and SGS, our production lines bridge the gap between heavy industrial requirements and strict environmental standards.
Understanding the fundamental crystalline structures, kinetics of selective adsorption, and chemical stability of type 13x zeolites.
Zeolite 13x is the sodium-form (Na+) of the Type X crystal structure, presenting a faujasite (FAU) structural topology. The effective pore opening of 13X is approximately 10 Angstroms (1.0 nm), enabling the co-adsorption of molecules with larger kinetic diameters than those processed by 3A, 4A, or 5A structures.
Featuring a theoretical chemical formula of Na86[(AlO2)86(SiO2)106]·xH2O, this matrix exhibits high electrostatic selectivity. It targets compounds with strong quadrupole moments or high polarizability, such as carbon dioxide (CO2), hydrogen sulfide (H2S), and heavy mercaptans.
Due to optimized macro- and meso-porous pathways constructed during the pelletization process, Jiuzhou's 13x molecular sieves decrease diffusion resistance, ensuring tight mass transfer zones (MTZ) and maximizing breakthrough times in high-pressure columns.
In cryogenic air separation units (ASUs), the primary purification step must remove moisture and carbon dioxide down to parts-per-billion (ppb) levels to prevent heat exchanger freeze-ups. Zeolite Molecular Sieve 13x (especially the 13x-APG grade) provides an optimized adsorption isotherm for CO2, even at low partial pressures. The adsorption occurs via physical coordination with the intra-crystalline sodium cations, allowing for fully reversible thermal regeneration (TSA) or pressure regeneration (PSA) cycles.
Furthermore, because the pore diameter is 10Å, it acts as a primary stage filter for heavy organic impurities, ensuring downstream safety in air separation systems handling volatile compounds or hydrocarbons. This dual purification capacity—removing both polar, highly reactive inorganic molecules and complex volatile compounds—is why 13X remains the industrial standard across petrochemical and gas extraction complexes globally.
How industries across North America, Europe, Asia, and emerging markets integrate our 13x Molecular Sieve systems.
In the US Gulf Coast, 13x molecular sieves are deployed in natural gas sweetening packages. By removing traces of H2S, mercaptans, and CO2, they safeguard expensive cryogenic liquefaction equipment from corrosion, hydrate formation, and freezing blockages.
Europe's rigorous environmental directives require carbon scrubbing from raw biogas to produce grid-compliant biomethane. Our specialized 13x sieves selectively capture carbon dioxide while leaving methane molecules untouched, achieving methane purities exceeding 98%.
With the surge in decentralized medical facilities across India and Southeast Asia, PSA oxygen generators rely heavily on 13x-HP (High Performance) molecular sieves to selectively adsorb nitrogen, enriching oxygen to 93%–95% for hospital patient distribution networks.
The industrial landscape for molecular sieves has shifted from simple local procurement to global supply chain integration. The demand for 13X is highly correlated with capital-intensive infrastructure projects such as oil refineries, steel manufacturing plants, and clean energy storage sites. Due to the high cost of process downtime, corporate engineering firms place extreme emphasis on the structural integrity of the adsorbents—specifically focusing on *crush strength* and *attrition rate* metrics.
If a low-cost, uncertified molecular sieve is loaded into a large-scale dryer, the physical stress of cyclic pressure swings will cause the beads to pulverize. This leads to channeling, increased pressure drops across the vessel, and premature breakthrough of water or acid gases, which could destroy downstream catalysts worth millions of dollars. Our manufacturing focus at Jiuzhou centers on resolving this vulnerability through advanced clay binder engineering and uniform kiln firing processes.
Our dual-production architecture safeguards lead times and ensures continuous supply chain options for global buyers.
Our primary facility in Shanghai focuses on synthetic zeolite powder cultivation and specialized molecular sieve extrusions. Housing our core R&D laboratory, Shanghai acts as the quality gatekeeper, performing dynamic adsorption testing, particle size distribution analysis, and structural crystallinity monitoring via X-ray diffraction (XRD).
The Wuxi facility is optimized for mass manufacturing and calcination scaling. Equipped with high-capacity rotary kilns and advanced spherical forming machinery, Wuxi processes large-volume runs of standard Zeolite 13x and Activated Alumina. This site features specialized dust-free packaging rooms capable of processing inert-gas flushed steel drums and heavy industrial super bags.
How the evolution of molecular sieves is shaping CCUS (Carbon Capture) and green hydrogen technologies.
As the global energy landscape transitions toward carbon neutrality, the demands placed on molecular sieves are undergoing a paradigm shift. Zeolite 13x sits at the center of this transformation, particularly in Carbon Capture, Utilization, and Storage (CCUS) projects and the purification of green hydrogen.
