Explore our premium select catalog engineered for chemical separation, environmental treatment, and process stabilization.
Located in the premier economic development hub of Shanghai, Shanghai Jiuzhou Chemicals Co., Ltd. has stood at the forefront of chemical innovation since its establishment. Guided by our foundational principles of "Quality Control & Continuous Innovation", we specialize in the development, research, and high-precision manufacturing of molecular sieves, active powders, activated alumina, and structural packing elements.
Our fully automated factories, certified under the ISO9001:2008 system alongside rigorous TUV & SGS frameworks, run with advanced dynamic testing labs. From chemical adsorption to support media engineering, we empower industrial leaders worldwide with localized supply channels, custom active-phase synthesis, and zero-downtime integration consultancy.
Optimizing thermodynamic performance, attrition resistance, and chemical conversion across diverse manufacturing fields.
Used as inert support bed media for catalytic reforming, hydrodesulfurization, and hydrocracking. The high alpha-alumina phase composition guarantees thermal shock resistance at temperatures exceeding 1350°C while preventing silica contamination of catalysts down-stream.
Activated Alumina Spheres act as the key desiccant matrix in heatless/thermal regeneration adsorption compressed air dryers. Offering stable dew point control down to -70°C, these spheres maintain high mechanical strength under high moisture load cycles.
Specifically modified alumina carriers capture hazardous gaseous contaminants including Hydrogen Fluoride (HF), Chlorine (Cl2), and organic sulfides. Active active-phase distributions improve absorption rates and cycle lifetimes in toxic environments.
A deep dive into mineral structures, structural configurations, and chemical composition thresholds driving industrial efficiency.
Under extreme industrial process conditions (high temperature, high pressure, acid/alkali exposure), the performance of support media is determined by phase composition. Pure Alpha Alumina ($\alpha$-Al₂O₃) features a close-packed hexagonal crystal system, which provides excellent resistance to thermal deformation, chemical corrosion, and mechanical crush loads.
In contrast, Activated Alumina ($\gamma$-Al₂O₃) features a highly porous cubic structure, providing a high specific surface area (up to 360 m²/g) optimize for physical adsorption, catalyst deposition, and active agent retention.

Our commitment to local communities, ecological sustainability, and carbon emission reductions in clean air technologies.
A proactive view into tomorrow’s requirements: zero-dust structures, catalytic activity, and low-regeneration-energy materials.
By using template-assisted hydrothermal pathways, we are developing alumina structures with targeted pore sizes. This allows for selective hydrocarbon adsorption while preventing cracking in gas treatment cycles.
Pneumatic conveying in modern processing plants can cause dust generation from alumina media. Our upcoming line of active spheres utilizes structural binders that reduce dust formation by up to 40% compared to traditional models.
Aligning with carbon neutrality goals, we are modifying our calcination kilns to integrate thermal energy recovery. This reduces carbon emissions during alumina phase transition processing by up to 22%.
