JOOZEO pitches PSA adsorbent for hydrogen purification in China

Shanghai Jiuzhou Chemicals said its JZ-512H molecular sieve is designed for PSA hydrogen purification, with published adsorption data for CO, methane and nitrogen. The company is positioning the material for operators that need to separate upstream hydrogen generation from downstream purification.

Why it matters: - Hydrogen projects depend on more than generation. Final fuel quality also hinges on downstream purification. - JOOZEO is targeting that purification step with a molecular sieve it says is built for carbon monoxide, methane and nitrogen removal in PSA systems. - The company is also providing adsorption and mechanical data that procurement teams can use to compare materials for hydrogen beds.

What happened: - Shanghai Jiuzhou Chemicals Co., Ltd. (JOOZEO) published technical guidance for China hydrogen production buyers focused on PSA purification. - The company said the JZ-512H molecular sieve is intended for PSA hydrogen purification, carbon monoxide refining and normal/isoparaffin separation. - JOOZEO pointed buyers to its website for PSA hydrogen purification resources and JZ-512H specification data: the official website.

The details: - JOOZEO said hydrogen procurement should separate upstream generation, such as steam methane reforming or electrolysis, from downstream PSA purification. - The PSA process uses pressure swings between adsorption and desorption stages to trap impurities and release purified hydrogen. - JZ-512H uses a calcium-sodium aluminosilicate structure with a 5-Angstrom pore size. - The sieve is designed to admit molecules no larger than 5 Angstroms. - JOOZEO listed minimum adsorption values of 30 ml/g for carbon monoxide, 16 ml/g for methane and 10 ml/g for nitrogen. - JOOZEO said oxygen adsorption is limited to no more than 3.4 ml/g. - The company said the material has a spherical particle size of 1.6–2.5 mm, attrition of no more than 0.15%, crush strength of at least 45 N per piece and bulk density of at least 0.75 g/ml.

Between the lines: - The pitch is less about broad filtration and more about a narrowly defined engineering use case. - JOOZEO is trying to make adsorbent selection look like a technical procurement decision, not a generic commodity buy. - The emphasis on feed-gas composition, pressure, temperature and cycle timing suggests the company wants buyers to match the material to specific plant conditions before purchase.

What's next: - JOOZEO said project teams should share inlet composition, flow rates, temperatures, adsorption and desorption pressures, and cycle times before selecting a product. - The company said it expects suppliers to provide technical data sheets, packaging, storage protocols and loading guidance in return. - Procurement teams evaluating PSA systems will likely use those inputs to decide whether JZ-512H can run alone or needs pre-treatment or layered-bed configurations.

The bottom line: - JOOZEO is framing JZ-512H as a traceable PSA adsorbent for hydrogen purification, backed by impurity-specific performance data and handling specs.
