Abstract

DIRECT REDUCED IRON FROM BIOMASS. The present invention relates to a process for producing direct reduced iron ("DRI") from iron ore and biomass in a single-stage fluidized bed characterized by injecting (a) iron ore, (b) gaseous oxygen and (c) a solid reducing agent including biomass into a reaction zone of the fluidized bed operating in a temperature range of 750-850°C and reducing iron ore and forming DRI in the fluidized bed and discharging DRI exhibiting a metallization of at least 70% of the fluidized bed.
