By consolidating a world-class chemical engineering research division with dynamic test laboratories, Jiuzhou provides highly optimized, energy-saving, and eco-friendly gas purification and adsorption systems. Today, our products form the operational backbone of global refining, air-separation, and process industrial sites.
Jiuzhou operates dedicated, high-output production plants designed around automation, closed-loop safety configurations, and stringent environmental protections.
Our Shanghai headquarters operates as the nerve center for advanced material research, product customization, and standard formulation. It focuses on the production of specialized chemical formulations, technical support, and premium molecular sieve processing, integrating automated packaging and comprehensive quality-control loops to serve key international logistics hubs.
The Wuxi production complex houses massive rotary calcination kilns, spherical forming machines, and automated grading systems. By implementing high-level process automation, the Wuxi site enables high-volume manufacturing of activated alumina and inert support packing, ensuring raw materials are transformed into durable adsorbents with exact pore sizes and high mechanical integrity.
Jiuzhou Chemicals does not merely follow chemical industry standards—we actively write and define them. Through extensive participation in national committees, we contribute to establishing testing guidelines and specifications.

Low-carbon production guidelines for industrial chemical enterprises.
Adsorption science is critical to energy transition, carbon capture, and green chemical engineering. Our technical roadmap defines how next-generation materials achieve high performance.
By shifting from conventional thermal precipitation to precision calcination, we control the formation of gamma-phase alumina crystals. This approach optimizes the distribution of micro, meso, and macropores, which helps minimize capillary condensation and enhances gas diffusion kinetics in fast-cycle industrial dryers.
We are integrating low-carbon calcination methods into our Wuxi factory. Through recovery of waste heat from rotary kilns and the use of bio-based binders, our roadmap aims to reduce the carbon footprint of activated alumina production by 30% by 2028.
Future systems require dynamic capability. We are developing structured hybrid spheres that combine silica-gel cores with activated alumina shells. These hybrids are designed to process wet air streams containing high relative humidity without structure collapse or attrition.
We provide engineered solutions designed to keep industrial operations running efficiently, protect processing equipment, and reduce down-time.
In petrochemical processing, acid gases and trace moisture can degrade downstream polymerization catalysts. Our Claus catalysts and acid scavengers remove trace HF, HCl, and organo-sulfur compounds. This maintains clean pipelines, avoids corrosion, and prevents catalyst poisoning.
For industrial compressed air networks, moisture condensation leads to corrosion, valve failure, and system downtime. We supply customized spherical activated alumina that maintains low dew points (down to -70°C). High crush strength prevents dusting, keeping air lines clear.
High fluoride and arsenic levels pose health risks in regional water supplies. Our activated alumina serves as an effective adsorption medium for fluoride, selenium, and heavy metal removal. It features high adsorption capacity, physical stability, and supports multiple regeneration cycles.
By modernizing our manufacturing base through digital transformation, Jiuzhou Chemical guarantees stable production volumes, consistent batch quality, and secure supply chains for global buyers.
Our raw material batching and rotary calcining systems are managed by centralized DCS networks. Real-time temperature sensors and automated feeders regulate calcination within a ±2°C range. This process control ensures that every batch of activated alumina matches specific pore structure and crush-strength criteria.
Located near the deep-water port of Shanghai, our supply chain is designed for reliable international transport. We maintain automated inventory management systems that synchronize production schedules directly with shipping dates, helping to minimize handling delays and export lead times.
Through partnerships with domestic bauxite refineries, we secure consistent raw material supplies. This direct access to high-purity aluminum hydroxides helps insulate global procurement partners from volatile raw material price spikes and supply disruptions.
We align our operational model with the commercial, technical, and regulatory requirements of international corporate purchasing groups.
Solution: We enforce statistical process control (SPC) across all manufacturing runs. Each shipped batch is accompanied by an authentic certificate of analysis (COA) specifying surface area, pore volume, crush strength, and particle size distribution.
Solution: Spherical dust and broken beads can clog downstream system filters. We utilize multi-layer composite packaging and reinforced steel drums to minimize vibration damage during transit, ensuring adsorbents arrive ready for loading.
Solution: Our technical team assists customers with adsorbent sizing, bed configuration, and regeneration calculations. This helps ensure you select the appropriate material grade for your specific process temperature and flow rate.
Operating in global markets requires compliance with regional safety, environmental, and trade standards.
Jiuzhou chemical products are certified under REACH (Europe) and TSCA (USA) frameworks. We provide complete Safety Data Sheets (SDS) in multiple languages to support local environmental and occupational safety compliance during import and handling.
Our distribution network covers key regions in the United States, Southeast Asia, Japan, Europe, and the Middle East. This network enables us to handle international inquiries quickly, manage shipping logistics, and assist with technical service requests.
We work to align our manufacturing practices with global sustainability goals. This includes using closed-loop water systems in our factories, implementing safe waste-disposal protocols, and offering recyclable bulk packaging options.
We believe in the power of chemical engineering to clean the environment, purify the atmosphere, and deliver a cleaner world for future generations.

Activated alumina is a porous form of aluminum oxide featuring high physical strength and resistance to liquid water, making it suitable for high-moisture air drying. Silica Gel offers high capacity at low temperatures but can disintegrate in liquid water. Molecular Sieves are crystalline aluminosilicates designed for selective separation based on precise molecular size (e.g., 3Å, 4Å, 10Å).
Regeneration is typically achieved by heating the bed to 150°C - 250°C to release adsorbed moisture. Heating duration, purge gas flow rate, and pressure swing cycles are key parameters for restoring adsorption capacity.
Yes. Activated alumina exhibits high affinity for fluoride and arsenic ions under optimized pH conditions (typically between 5.5 and 6.0). When the bed reaches capacity, it can be regenerated using a dilute sodium hydroxide solution followed by acid neutralization.
We monitor calcination, forming, and sorting steps using automated process control systems. Every shipment undergoes standardized testing, and we provide a Certificate of Analysis (COA) for key performance metrics.
Our standard export packaging options include triple-layer moisture-resistant bags, heavy-duty fiber drums, and steel drums with moisture-barrier liners. For volume shipments, we offer bulk super sacks on pallets.
In standard compressed air dryers, a charge of high-quality activated alumina typically operates for 2 to 5 years. Lifespan depends on feed-gas contamination levels (e.g., lubricating oil carryover) and regeneration temperature control.
