Explore our industrial desiccants, catalysts, and molecular sieves deployed in standard-critical systems globally.
A legacy of quality control, persistent innovation, and top-tier chemical product engineering.
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 principles of "Quality Control & Innovation", committing resources to the development, rigorous research, and large-scale manufacturing of high-quality, innovative chemical solutions.
Our main products span various molecular sieve powders, molecular sieves, activated powder, activated alumina, aluminum oxide catalysts, different types of alumina packing, ceramic balls, sodium silicates, aluminum hydroxide, zeolite 4A, sodium carbonates, and SLES, among other high-grade chemical materials. To ensure absolute compliance and consistent batch quality, all of our products have passed the ISO9001:2008 quality management system certification along with authoritative TUV & SGS Certifications.
By leveraging international-standard production technologies and highly specialized laboratory facilities, Jiuzhou stands at the forefront of the global chemical supply chain, delivering tailored adsorption and catalytic solutions that lower carbon footprints and minimize utility costs for industrial facilities.
Analyzing key structural shifts, supply stability, and chemical engineering requirements for industrial buyers.
Modern PSA (Pressure Swing Adsorption) systems and chemical scrubbers require carbons with specific pore distribution, low ash levels, and high mechanical hardness to prevent dust attrition and premature system breakdown.
With regulations like REACH in Europe and local EPA policies globally, industrial procurement teams prioritize suppliers with documented quality credentials, uniform bulk densities, and verified activation origins.
Direct sourcing from established Chinese factories provides scalable manufacturing capacity, competitive bulk pricing, and specialized custom modifications (such as pelletized, granular, or acid-washed configurations).
Macro-Industry Market Demands: Today's global market calls for multi-functional adsorbents capable of treating heterogeneous waste streams. From gas-phase separation to volatile organic compound (VOC) recovery, procurement directors look beyond generic suppliers. They seek specialized production facilities equipped with dynamic testing laboratories that can simulate breakthrough curves and target adsorption rates.
As standard-setters in several chemical testing categories, Shanghai Jiuzhou Chemicals provides the technical framework necessary to customize porosity (microporous, mesoporous, and macroporous) based on the target adsorbate size. This results in superior mass transfer kinetics, longer bed life, and lower pressure drop across industrial vessels.
Addressing the ESG Challenge: Global industrial operations are actively monitoring the scope emissions associated with their manufacturing chains. Utilizing high-efficiency activated alumina, molecular sieves, and custom-engineered carbon carriers reduces utility energy requirements in regeneration cycles.
By optimizing the thermal swing regeneration profiles of our adsorbents, we assist operations in meeting their sustainability goals while ensuring maximum gas dryness and purity levels (e.g., dew points down to -70°C in compressed air systems).
Operating dedicated workshops and standard-compliant facilities to secure steady product output and flawless QC.
Our central hub focused on research, advanced chemical synthesis, and international quality management protocols.
Large-scale automated workshop designed for high-capacity batch runs, packing, and global distribution logistics.
A closer look at raw material optimization, thermal activation pathways, and targeted pore tailoring.
Whether utilizing high-density coconut shells, premium anthracite coal, or select wood matrices, we control the precursor properties to establish base hardness and structural framework.
Our plants use precise steam or chemical activation in rotary kilns. By controlling temperature profiles (800°C - 1000°C) and dwell times, we develop uniform internal pore networks.
For specialized gas scrubbing (H2S, acid gases, ammonia), we chemically modify the carbon surface with targeted dopants to enhance chemisorption properties alongside physisorption.
Our commitment to sustainable production, waste minimization, and eco-friendly chemical processes.
Shanghai Jiuzhou Chemicals actively leads and participates in defining national and group benchmarks for chemical adsorbents.

Understanding the micro-pore engineering that permits nitrogen generation through pressure swing adsorption.
The Separation Mechanism: Unlike typical granular activated carbons that adsorb contaminants via broad pore structures, Carbon Molecular Sieves (CMS) are engineered with highly specialized, uniform micro-pores. These pores measure in the range of angstroms (approx. 3 to 5 Å). Oxygen molecules, having a smaller kinetic diameter than nitrogen molecules, diffuse into the internal pore structure of the CMS at a much faster rate, allowing high-purity nitrogen to flow out as the product gas stream.
Our CMS Innovations: Jiuzhou has developed and optimized multiple CMS variations, including JZ-CMS4N, JZ-CMS6N, JZ-CMS8N, and the specialized JZ-CMS3PN. These products feature extremely high nitrogen yields, outstanding mechanical strength (preventing pulverization during rapid valve actions in PSA beds), and long-term performance stability. This translates to reduced energy consumption in nitrogen generators because less air must be compressed to yield the same volume of pure nitrogen.
Application Focus: Our carbon molecular sieves are extensively utilized in food preservation packaging, electronics manufacturing, marine transport blanketing, oil & gas storage purge systems, and coal mine fire prevention. By optimizing pore size distribution at the manufacturing stage, we achieve exceptional recovery rates and oxygen-adsorption capacities.
To ensure peak performance, our quality team tests every batch using a custom-designed dynamic testing apparatus that replicates actual PSA working conditions. This level of verification gives global engineering procurement teams confidence in the operational longevity and yield of our products.
