On-Site Production of High-Calorific Hydrogen-Rich Fuel Gas

Stable supply of hydrogen-rich fuel gas can be realized via mature methanol reforming technology. We match every methanol reformer according to factory waste heat, gas flow demand, natural gas blending ratio and site space, which well fits the construction of hydrogen production plant and green hydrogen plant.

HYVODA DDH-R hydrogen gas generator is customized methanol reforming equipment for industrial low-carbon transformation. The methanol reformer outputs mixed gas with over 95% combustible components, and supports dual heating modes: electric heating or waste heat recycling from production lines. This hydrogen generator effectively cuts fuel cost and carbon emissions, while avoiding storage risks of high-purity hydrogen for boiler heating and pipeline blending projects of Green Hydrogen Production Plant.

Methanol Reforming Technology for Combustible Fuel Gas

Methanol reforming is the most cost-effective route for mass industrial fuel gas supply. The core reaction inside the methanol reformer is steam reforming of methanol, also known as reforming methanol. This hydrogen gas generator directly produces hydrogen-rich syngas without PSA purification, simplifying the whole flow and lowering power consumption. Two heating options are available: built-in electric heating for factories without residual heat, and external waste heat utilization to save heating energy. Single unit output ranges from 30 to 1000 Nm³/h, and multiple sets can run in parallel to satisfy large-scale green hydrogen plant demand.

Fully Integrated Explosion-Proof Skid Assembly

The DDH-R hydrogen generator integrates methanol feeding, vaporization and methanol reformer into one explosion-proof skid. All modules finish assembly, pressure test and 72-hour continuous operation test before delivery, supporting fast deployment for hydrogen production plant and gas blending projects.

HOW IT WORKS

Dual-Heating Methanol Reforming Process

Feed Mixing & Vaporization: Industrial methanol is metered and vaporized by built-in electric heater or factory surplus waste heat
Catalytic Methanol Steam Reforming: Preheated methanol vapor reacts on dedicated catalyst inside methanol reformer via reforming methanol reaction to form hydrogen-rich crude syngas
Cooling & Condensation: High-temperature syngas cools to ambient temperature; unreacted methanol condensate recycles back to raw material tank
Direct Fuel Gas Output: Syngas is delivered to boilers, kilns or blending pipelines without PSA purification
Residual Heat Recycling: Heat separated from syngas is reused to preheat raw methanol and reduce energy consumption of methanol reforming

FAQ’S

What gas composition can DDH-R hydrogen generator produce?

The methanol reformer produces syngas with 65–75 vol% hydrogen and over 95% total combustible components. No PSA purification required; the gas can be directly used for natural gas blending and heating of green hydrogen plant.

Can this methanol reformer run on factory waste heat instead of electric heating?

Yes, the hydrogen generator supports dual heating modes. Factories with surplus steam or waste heat can cut electric load for methanol reforming and lower overall operating cost.

Does the DDH-R hydrogen gas generator need full-time operators?

No continuous manual supervision needed. The whole methanol reformer runs under automatic PLC control with remote monitoring and safety interlock protection. We provide systematic training on methanol reforming operation for your technicians to finish daily maintenance of hydrogen production plant.

Can gas flow, pressure and skid layout be customized for our green hydrogen plant?

All DDH-R hydrogen generator can be tailor-made on gas throughput, outlet pressure and cabinet layout, matching fuel blending demand and limited space of Green Hydrogen Production Plant.

How long is the on-site installation cycle?

All methanol reformer core modules finish factory testing before delivery. Pipeline connection and system debugging can be completed within 1–2 weeks for hydrogen production plant construction.

What about operating noise of the DDH-R hydrogen generator?

Fully enclosed sound insulation limits noise below 75dB(A) at 1m, suitable for indoor workshops and outdoor green hydrogen plant deployment.

What is the maintenance cycle of the methanol reformer?

Monthly inspection and quarterly calibration are required for the hydrogen gas generator; core catalyst for methanol reforming only needs replacement after several years of stable operation.
