A process for producing iron carbide in a fluid bed reactor in which the pressure may be maintained in excess of the pressure at which the mole fraction of hydrogen in the process gas begins to decrease. The hydrogen concentration is increased above the equilibrium concentration for hydrogen at the temperature and pressure in the reactor. Further improvements are gained by preheating a iron ore reactor feed in which the iron oxide is primarily in the form of hematite under a reducing atmosphere, and using at least two fluid bed reactors in series.

[ What is claimed is:] [1.] In a process of producing iron carbide in a fluid bed reactor comprising introducing an iron oxide containing reactor feed into a fluid bed reactor, contacting said feed in said reactor with a reactant gas comprising a reducing gas and a carburizing gas to convert at least a portion of said feed to iron carbide, the improvement wherein said iron oxide in said feed is at least about 90% hematite and said feed is preheated in a reducing atmosphere prior to introduction into said reactor, and wherein at least about 50% of said hematite is reduced to magnetite prior to introduction into said fluid bed reactor.
