A process for converting iron oxide to iron carbide using hydrogen as a reducing gas. Water is generated by the reduction of the iron oxides using hydrogen. The amount of water present in the reactor system is controlled and the water is contacted with methane in order to internally generate carbon monoxide and/or carbon dioxide gas. The carbon monoxide and/or carbon dioxide is subsequently employed to carburize the iron to iron carbide.

On décrit un procédé de conversion d'oxyde de fer en carbure de fer, dans lequel on utilise de l'hydrogène en tant que gaz réducteur. On produit de l'eau lors de l'étape de réduction des oxydes de fer au moyen d'hydrogène. On régule le volume d'eau présent dans le système du réacteur et on met cette eau en contact avec du méthane de manière à produire in situ un gaz de monoxyde de carbone et/ou de dioxyde de carbone. On utilise ensuite ce monoxyde de carbone et/ou ce dioxyde de carbone pour carburer le fer et obtenir du carbure de fer.
