High-purity gas deep purification solution | Dalian Chuangge 506HL palladium catalyst + dedicated desiccant molecular sieve, one-button operation achieves residual oxygen <1ppm
With the large-scale development of the green hydrogen industry, as well as advancing standards for high-purity gas supplies in the electronics, semiconductor and special material manufacturing sectors, water electrolysis hydrogen production, circulating purification of inert gases and high-purity gas treatment systems have long been plagued by two core challenges. Trace oxygen in feed gas cannot be deeply removed, and water vapor generated by deoxygenation reactions remains in the pipeline. The combination of these two impurities easily triggers equipment corrosion, poisoning of catalytic components and oxidation & scrappage of downstream finished products. Substandard gas purity directly reduces production line yield and greatly increases operation & maintenance costs as well as raw material consumption expenses.
To realize integrated deep deoxygenation and simultaneous dehydration, and stably reduce the oxygen content of various process gases to below 1 ppm, Dalian Chuangge offers a combined purification packing consisting of 506HL Palladium Catalyst and supporting water removal molecular sieves. This complete set matches full-process purification for hydrogen deoxygenation, nitrogen deoxygenation via hydrogen addition, and purification of inert gases including argon, helium and carbon dioxide. It delivers an integrated and high-efficiency purification solution for post-processing purification of water electrolysis hydrogen, inert gas circulation in glove boxes, high-purity gas supply for electronics and special chemical gas treatment.
I. 506HL Palladium Catalyst: High-Activity Deep Deoxygenation, Residual Oxygen Consistently Below 1 ppm
Trace oxygen in gas constitutes the key bottleneck restricting high-purity gas quality. Crude hydrogen produced by water electrolysis inherently contains trace oxygen impurities, while oxygen permeates into inert gases such as nitrogen and argon through pipelines. Conventional simple deoxygenation fillers can only lower oxygen content to dozens of ppm, failing to meet stringent low-oxygen requirements for fuel cells, semiconductors, lithium battery materials and vacuum coating.
Dalian Chuangge 506HL Palladium Catalyst adopts precious metal palladium supported on modified alumina carriers and is shaped into spherical pellets via self-developed high-temperature loading technology, featuring prominent core advantages:
It boasts ultra-high catalytic activity and ultimate deoxygenation depth. The hydrogen-oxygen catalytic reaction initiates at room temperature (with higher efficiency under heated conditions). For feed gas with oxygen content ≤ 2%, residual oxygen after single-stage bed treatment is stably controlled within 1 ppm, and can drop below 0.5 ppm under optimal operating conditions, fully complying with national standards for high-purity hydrogen and ultra-high-purity inert gases. Relying on palladium-based catalysis to accelerate the reaction 2H₂+O₂=2H₂O, it requires no frequent activation pre-treatment. Production can start immediately after packing and nitrogen purging, simplifying equipment operation workflows.
High Throughput & Wide Operating Condition Adaptability for Continuous Production Lines
It allows a space velocity ranging from 5,000 to 10,000 h⁻¹, operating stably in high-flow hydrogen purification equipment and large-scale inert gas circulation glove boxes. It features a wide temperature resistance range, resisting ablation and sintering under short-term high temperatures, and accommodates variable-load, intermittent and 24-hour continuous production modes.
High Mechanical Strength, Low Pulverization Risk & Extra-Long Service Life
Each spherical pellet features a compressive strength of ≥ 80 N, remaining intact without pulverization during packing and gas flow scouring to avoid pipeline and filter blockage. It demonstrates stronger resistance to poisoning by hydrogen sulfide, ammonia and acidic impurities compared with ordinary palladium catalysts. Under normal operating conditions, its service life exceeds 3 years, drastically cutting filler replacement frequency and production downtime losses.
Universal Compatibility with All Gas Types for Multi-Scenario Deoxygenation
Not limited to water electrolysis hydrogen purification, it is also applicable to nitrogen deoxygenation with hydrogen addition and oxygen removal from inert gases including argon, helium and CO₂. A single type of packing can be flexibly switched between multiple gas production lines, lowering spare parts inventory costs for enterprises.
II. Matching Special Water Removal Molecular Sieves: Complete Elimination of Water Vapor Byproducts from Deoxygenation to Prevent Secondary Contamination
Palladium-catalyzed deoxygenation continuously generates water vapor. If palladium catalyst is used alone, residual water vapor in pipelines will trigger a chain of hidden hazards: corrosion of stainless steel reactors, failure of downstream precision filter elements due to moisture, oxidation of lithium battery & electronic materials upon water contact, and premature adsorption saturation of molecular sieve fillers.
Dalian Chuangge’s custom supporting water removal molecular sieves form an optimal front-and-back matching combination with the 506HL Palladium Catalyst to achieve integrated deoxygenation and deep drying:
Selective Adsorption of Water Molecules Without Consuming Valuable Process Gases
Its pore size precisely matches the molecular diameter of water, selectively capturing trace water vapor generated in deoxygenation while producing no adsorption loss of primary gases such as hydrogen, nitrogen and argon, guaranteeing gas recovery rate and drastically lowering the dew point of treated gas.
High Adsorption Capacity & Stable, Recyclable Regeneration
After reaching adsorption saturation, complete regeneration can be achieved through hot purging at 200–300°C. Multi-tower switching purification systems enable uninterrupted continuous gas supply with low regeneration loss and no obvious attenuation of adsorption performance after long-term operation.
Uniform Particle Dispersion & Excellent Flow Performance After Packing
Free of fine dust, it forms evenly distributed gas flow within packed beds, eliminating channeling and biased flow that lead to substandard purification results. It is compatible with small & medium integrated purification machines and large skid-mounted hydrogen purification equipment.
III. Combined Packing Set for High-Purity Gas Treatment Systems Across All Industries
The front-to-back matching of 506HL Palladium Catalyst and water removal molecular sieves forms a standardized purification unit, widely applied across new energy, electronics, advanced materials and chemical industries:
✅ Post-processing Purification Systems for Water Electrolysis Hydrogen
Deep purification of crude hydrogen from alkaline (ALK) and proton exchange membrane (PEM) electrolysis to remove oxygen byproducts and reaction water vapor, producing 99.999% high-purity hydrogen for fuel cells, hydrogen energy storage and metal smelting.
