Dissociateur Méthanol pour la production d'hydrogène (H2) et de monoxyde de carbone CO

Beside endothermic gas or endo gas, more and more methanol is used for the thermal treatment of metals as a protective gas.

  Mayor reactions
  CH3OH  →  CO  +  2 H2
  H2O + CO  →  CO2  +  H2

  Summary reaction
  CH3OH + H2O  →  CO2  +  3 H2

Carbon monoxid and hydrogen are formed. The methanol cracking gas (CH3OH) is an excellent carrier gas.
Hydrogen and carbon monoxide are reducing agents and avoid oxidation or corrosion of metal surfaces in a furnace. It has to be taken into account however, that carbon monoxid increases the carbon content of steel. Methanol cracking gas can therefore be used for surface hardening of steel by carbonisation or carburization. Carbon concentration can be increased up to the saturation level of austenite in surface close areas (around 1mm deep). In order to control the carbonization, water vapour can be added or nitrogen can be used for dilution.
