The hydrogen generation plant based on methanol reforming with subsequent purification is a well-established process for hydrogen production and the alternative method at locations with limited access to hydrocarbons.
Basic process steps:
Methanol water mixture is vaporized and converted to hydrogen rich synthesis gas in the tubular thermal-oil heated reactor over copper catalyst. Synthesis gas from reactor outlet is cooled down, condensate is recycled and the hydrogen rich gas is purified using HYDROSWING PSA technology.

With the use of thermal oil the hydrogen production plant will keep its operating temperature extremely stable and can be restarted at short notice e.g. if a power failure occurs. With Mahlers’ technology and design an overheating of the reactor and the low temperature catalyst, which is highly temperature sensitive is prevented by using a heat transfer media (thermal oil) buffering any temperature peaks. This helps to protect the catalyst for the complete lifetime.
At Mahler-plants the ignition of the burners is done automatically from the control container/room, no manual ignition by an operator is necessary. Mahler designs tailor-made and standard plants and has already built more than 4500 plants worldwide.
From a reasonable and economical point of view the operating pressure of the Hydrogen-PSA-unit, as part of a hydrogen generation plant as well as for a stand-alone plant, should be between 10 and 30 bar(abs).
