    Direct Reduction Process an overview ScienceDirect Topics

    Natural gas cannot be used directly in the reduction of iron ore because it decomposes to form soot at a temperature below that which iron oxide can be reduced. Natural gas is used in three main ways: first, as a feedstock for producing the reducing gas, second as a fuel for supplying the necessary heat in the furnace and gas reformer, and third as a coolant and carburizing agent for freshly-prepared DRI.
