Abstract:
A process for conversion of iron oxide to iron carbide, comprising the steps of:providing a fluidized bed reactor having a metallizing zone and a carburizing zone;feeding iron oxide to said reactor;feeding a reducing gas to said reactor so as to provide reduced iron in said metallizing zone; andfeeding a carburizing gas to said carburizing zone wherein said reducing gas and said carburizing gas are fed to said reactor so as to provide a ratio (CH.sub.4 +CO)/CO.sub.2 of between about 9 and about 33 so as to provide a final iron carbide product in said carburizing zone having between about 2.2% wt. and about 6,5 wt. % carbon and at least about 91% wt. iron.
