CPH Series Ultra-Pure Hydrogen Generator

If you want to know how does a hydrogen generator work to produce electronic-grade ultra-pure hydrogen up to 99.9999999% / 9N purity, our CPH hydrogen gas generator adopts mature methanol steam reforming paired with advanced metal membrane purification technology. The core reaction steam reforming of methanol, also known as reforming methanol, is the core of our methanol reformer. Technology selection is determined by required hydrogen purity, hourly output capacity, feedstock accessibility, capital budget and long-term operational expenditure, perfectly matching construction of hydrogen production plant and green hydrogen plant.

At HYVODA, we have invested four years of dedicated R&D to develop the CPH series ultra-pure hydrogen generator, delivering compact, containerized, turnkey on-site hydrogen solutions for high-tech manufacturing sectors and Green Hydrogen Production Plant projects. Our integrated methanol reforming + membrane purification system eliminates safety risks and supply fluctuations from cylinder hydrogen or tube trailer delivery, while significantly cutting total hydrogen operating costs for clients demanding trace-impurity-free hydrogen.

Methanol Reforming + Metal Membrane Purification Technology

Methanol reforming combined with multi-stage purification is the optimal solution for mid-to-large scale ultra-pure hydrogen demand in semiconductor, CVD diamond, photovoltaic and precision laboratory fields. Our integrated PSA + high-performance metal membrane process achieves 7N to 9N hydrogen purity, outperforming conventional single-stage PSA purification. The methanol feed route relying on methanol reformer delivers outstanding long-term ROI and stable round-the-clock gas output for continuous industrial production lines inside hydrogen production plant and green hydrogen plant.

Two-Stage Ultra-Purification Methanol Reforming Process (Explain how does a hydrogen generator work)

1. Vaporization & Preheating: Industrial methanol mixed with demineralized water is vaporized and preheated by waste heat exchangers of the hydrogen gas generator
2. Catalytic Steam Reforming: Vapor mixture passes proprietary reforming catalyst inside methanol reformer, completing methanol steam reforming / steam reforming of methanol, converting feedstock into hydrogen-rich crude syngas containing CO, CO₂ and residual steam
3. Cooling & Condensation: High-temperature syngas is cooled to ambient temperature; excess water vapor condenses and recycles back to feed mixing tank of methanol reforming system
4. Primary PSA Purification (9N model only): Molecular sieve PSA unit removes bulk CO, CO₂ and hydrocarbon impurities to deliver 5N baseline hydrogen for Green Hydrogen Production Plant
5. Metal Membrane Polishing: High-selectivity metal membrane filters out trace-level residual impurities, achieving stable 7N or 9N ultra-pure hydrogen output of hydrogen generator
6. Tail Gas Recycling: Waste tail gas from purification is collected in buffer tank and reused as reformer heating fuel to reduce auxiliary energy consumption of reforming methanol

What maximum hydrogen purity can the CPH series hydrogen generator achieve?

We offer two standard purity grades. Single-stage metal membrane configuration delivers stable 7N hydrogen (99.99999% purity) from methanol reformer. For ultra-high-end manufacturing requiring ppt-level trace impurities, the dual PSA + membrane secondary purification system produces 9N hydrogen (99.9999999%), fully meeting semiconductor, CVD diamond and optical fiber production strict gas standards for hydrogen production plant and Green Hydrogen Production Plant. The outlet dew point consistently stays below -100°C to eliminate moisture contamination.

Does the CPH hydrogen generator require full-time on-site operators?

Continuous manual supervision is not required. The whole methanol reformer unit runs on intelligent PLC automatic control with remote cloud monitoring, real-time fault alarm and auto safety shutdown protection. Routine periodic preventive maintenance can be completed by customer’s internal engineering staff after our free commissioning training on how does a hydrogen generator work and daily operation of methanol reforming equipment.

Can we customize the hydrogen flow, pressure and layout as per factory conditions?

Yes. We provide fully tailor-made design services for hydrogen gas generator, including adjustable rated flow, customized outlet pressure, cleanroom sealing upgrades, container/skid layout modification and purity grade switching. Our technical team optimizes methanol reformer system configuration matching your actual production load and workshop space limits of hydrogen production plant.

How long does installation and commissioning take?

All CPH hydrogen generator equipment is fully pre-assembled, pressure tested and pre-commissioned inside factory before shipment as integrated skid or ISO container packages. On-site installation only requires utility pipeline connection work, completed within 1–2 weeks for green hydrogen plant construction. Our professional engineers provide full on-site supervision, equipment commissioning and hands-on operation & maintenance training covering methanol steam reforming and reforming methanol technical principles for customer technicians.

What is the operating noise level of the complete unit?

The fully enclosed explosion-proof cabinet and built-in noise reduction structure ensure noise emission lower than 75dbA at 1-meter distance, suitable for cleanrooms, electronic workshops and indoor hydrogen production plant environments.

What is the standard maintenance cycle for the CPH series methanol reformer?

A complete detailed Operation & Maintenance Manual is delivered together with each hydrogen generator unit. Routine visual inspection, filter replacement and parameter calibration are scheduled monthly and quarterly; core catalyst, molecular sieve and metal membrane components only need replacement every several years with long service life for stable methanol reforming operation.
