Shanghai Jiuzhou Chemicals Co., Ltd. is strategically located in the largest economic development city, Shanghai. Over the years, Jiuzhou has consistently adhered to the core operating principles of "Quality Control & Continuous Innovation", committing ourselves fully to the design, synthesis, research, and global export of elite chemical products. Our diversified portfolio encompasses various molecular sieve powders, active molecular sieves, activated powder, premium activated alumina balls, customized alumina catalysts, structural alumina ceramic balls, sodium silicates, high-purity aluminum hydroxide, zeolite 4A, and environmental protection chemicals.
We boast a world-class R&D division staffed by leading minds in inorganic materials engineering and industrial adsorption science. Operating standard-compliant manufacturing lines, our operations are complemented by sophisticated analytical capabilities, including thermal gravimetric analysis, dynamic sorption testing, high-resolution XRD, and automated surface area analyzers.
Our premium-grade activated alumina spheres function as crucial elements in complex process engineering worldwide.
Highly effective in removing trace catalyst poisons, organic sulfur species, and moisture from liquid hydrocarbons, protecting downstream cracking units and catalytic reactors from premature degradation.
Assures continuous dew points as low as -70°C (-94°F) in dual-tower desiccant air dryers (PSA/TSA), avoiding line condensation and system freezing in critical automated process control configurations.
Serves as the benchmark working solution regenerator, absorbing degradation products, removing quinone impurities, and restoring active working chemicals for optimized cyclic synthesis efficiency.
Engineered with high surface area and structural integrity, our media outperforms standard desiccants under harsh operations.
