Discover our industrial-grade molecular sieves, silica gels, and activated alumina optimized for deep drying, separation, and purification.
Shanghai Jiuzhou Chemicals Co., Ltd., globally recognized under the trademark JOOZEO, is strategically based in Shanghai, the largest economic development and manufacturing hub in China. For three decades, Jiuzhou has consistently adhered to the core operational philosophy of "Quality Control & Continuous Innovation", committing its vast scientific and logistical resources to the development, manufacturing, and validation of high-end synthetic zeolites and adsorbents.
Our expansive product portfolio encompasses a diversified range of state-of-the-art chemical formulations, including specialized 3A, 4A, 5A, and 13X Linde-type molecular sieve powders, activated powder, highly active activated alumina, high-grade alumina catalysts, ceramic ball packing, sodium silicates, aluminum hydroxide, and related performance chemical agents. Every product batch is validated against stringent global standards, ensuring certifications like ISO9001: 2008, TUV, and SGS are continuously maintained.
By operating modern, multi-functional automated workshops and two advanced centralized laboratories equipped with dynamic testing facilities, JOOZEO bridges the gap between raw research and on-site performance. This reliable infrastructure allows us to build global partnerships, offering carbon-efficient and eco-friendly gas separation and liquid dehydration solutions to industrial users worldwide.
How we achieve operational reliability and technical innovation across our production sites.
JOOZEO deploys an automated operational framework that monitors manufacturing stages from raw silicate input to final kiln activation. Each production lot is cataloged and subjected to strict mechanical crush strength tests, nitrogen/oxygen adsorption capacity evaluations, and hydrothermal aging tests. By maintaining rigorous statistical control limits, we eliminate batch-to-batch variation, ensuring consistent pressure-swing adsorption (PSA) and thermal-swing adsorption (TSA) performance in the field.
We believe that standard chemical agents must evolve to meet modern decarbonization targets. Our R&D team works in close partnership with industrial engineering firms to develop customized pore sizes, high-density bead geometries, and attrition-resistant binders. This continuous cycle of innovation allows our catalysts and adsorbents to achieve lower pressure drop values and higher regeneration efficiencies, minimizing operating costs for our global customers.

Deep dive into the structural characteristics, adsorption dynamics, and engineering advantages of Linde-type aluminosilicate crystals.
Linde Molecular Sieves are synthetic crystalline aluminosilicates featuring highly regular, three-dimensional porous networks. The framework is composed of silica (SiO4) and alumina (AlO4) tetrahedra sharing oxygen atoms. The presence of aluminum creates a net negative charge on the crystal framework, which is balanced by mobile cations (typically Na+, K+, or Ca2+). By swapping these cations via precise ion-exchange processes, we control the pore opening sizes:
The efficiency of a Linde molecular sieve relies on its high affinity for polar molecules and its electrostatic field strength. Under high pressure, gas mixtures pass through the adsorption bed, where polar molecules like H2O and CO2 are captured in the crystalline voids. The non-polar components pass through unchanged, establishing a highly pure product stream. The system is then regenerated by heating (TSA) or lowering the pressure (PSA) to release the captured impurities.
Real-world implementations demonstrating the versatility and high performance of JOOZEO adsorbents.
Using JZ-ZT series 3A molecular sieves, petrochemical complexes remove trace moisture from cracked gas streams down to <1 ppm, preventing freezing and pipeline blockages in cryogenic separation units.
Our specialized molecular sieve beads are integrated within the spacer frames of double-glazed windows, absorbing residual moisture to prevent condensation and fogging over long lifespans.
JZ-ZHS and lithium-exchanged 13X molecular sieves are deployed in PSA oxygen concentrators, separating nitrogen from air to supply high-purity medical oxygen in hospitals and mobile health units.
In a volatile global market, secure chemical supply chains are essential for maintaining continuous operations. JOOZEO manages this by utilizing raw material reserves located near our Shanghai and Wuxi plants, insulating our clients from upstream pricing fluctuations.
Our manufacturing workflow features high-capacity rotary calcination kilns and automated pelletizing lines, allowing us to scale production up or down based on market demand. With a monthly capacity of thousands of tons, we handle large volume demands while keeping delivery times short.
Located near the Port of Shanghai, we offer streamlined shipping options via maritime, rail, and air logistics. This geographical advantage reduces ocean transit times and optimizes customs clearances, ensuring our materials arrive safely and on schedule at our clients' facilities.
