Hydrogen generation plant based on methanol reforming

Mahler AGS hydrogen plants based on methanol reforming process meet hydrogen requirements from 200 to 5.000 Nm³/h at purities up to 99,9999 vol.-% and typical product pressures from 10 bar to 30 bar(abs).


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.
