Engineered technical solutions meeting global purification, filtration, and drying specifications.
Activated Alumina ($Al_2O_3$) is a highly porous, transition-phase aluminum oxide structure featuring a vast internal surface area typically ranging between 250 to 350 m²/g. Due to its exceptional physical stability, thermal resistance, and chemical inertness, it remains the standard mass transfer agent for pressure swing adsorption (PSA) and temperature swing adsorption (TSA) systems.
Its unique performance is attributed to the presence of active hydroxyl groups on the crystalline surface, which behave as polar sites. These sites physically bind molecules such as water, heavy metals, and fluorides. Capillary condensation subsequently drives high-capacity moisture capture, ensuring consistent dew points as low as -70°C (-94°F) in critical compressed air systems.
As a leading Chinese chemical supplier, Jiuzhou integrates sophisticated manufacturing technologies to modify the pore-size distribution (mesoporous and macroporous) depending on application requirements, creating engineered media optimized for durability and high dynamic loading.
Delivering robust manufacturing and supply capability to continuous process industries worldwide.
Headquartered in the economic hub of Shanghai, Shanghai Jiuzhou Chemicals Co., Ltd. relies on advanced automated multi-functional workshops and a comprehensive analytical laboratory equipped with dynamic testing instrumentation. These assets ensure all batches conform to strict international benchmarks, supported by ISO 9001:2008, TUV, and SGS verifications.
We do not just follow standards; we actively help define them. Jiuzhou is a major contributor to key industrial frameworks.
Leveraging high production capacity, supply chain integration, and deep chemical expertise.
By operating key facilities within chemical industrial parks in Shanghai and Wuxi, Jiuzhou manages the entire transformation process from premium aluminum hydroxide feedstock to calcination, phase transformation, spherical forming, and final thermal activation. This ensures cost performance, reliable lead times, and structural consistency.
Global gas processing requirements differ by configuration, cycle times, temperature, and operating pressure. As an experienced OEM, we custom engineer key adsorbent characteristics. This includes tailoring target bead size distributions (e.g., 1/8", 3/16", 1/4"), maximizing crush strength, adjusting pore volume (cc/g), and optimizing chemical compositions.
Our centralized testing lab measures critical metrics including nitrogen adsorption-desorption isotherms (BET surface area), pore size distributions, attrition loss, bulk density, static water adsorption capacity, and dynamic breakthrough times. This approach verifies performance prior to container loading.
Jiuzhou operates production centers in both Shanghai and Wuxi, allowing us to manage production logistics efficiently. The Shanghai facility handles specialized chemical configurations, technical export logistics, and international custom engineering requests, while Wuxi focuses on volume-scale automated manufacturing of spherical activated alumina, molecular sieves, and catalysts.
The global adsorption market is transitioning from basic commodity desiccants to highly engineered material designs. Modern operations require materials with high chemical resistance, low energy regeneration demands, and extended operational lifespans to lower replacement costs.
Our commitment to sustainability, environmental management, and advanced chemical stewardship.
At Shanghai Jiuzhou Chemicals, our goal extends beyond producing effective industrial desiccants. We focus on environmental responsibility in our production and supply operations, ensuring our manufacturing sites comply with modern emission and energy-use guidelines.
Translating chemical engineering expertise into reliable solutions for complex purification processes.
Moisture in control lines causes corrosion and equipment downtime. Jiuzhou’s activated alumina adsorbents are used in dual-tower desiccant air dryers to control dew points under high pressures, protecting valves and instrumentation.
Water treatment programs utilize active alumina filtration beds to selectively adsorb excessive fluorides, arsenates, and selenium. This helps munipical and industrial sites comply with regional wastewater discharge standards.
Refining processes require the removal of acid residues, sulfur, and catalyst poisons from feed streams. Our adsorbents serve as protective guard beds, safeguarding downstream catalyst systems from premature deactivation.
