Sources of Reducing Gas

Various fuel sources can be used to create a suitable reducing gas for the MIDREX® Process.  These include natural gas, coal, coke oven gas or process syngas.


Reducing gas, containing mainly hydrogen (H2) and carbon monoxide (CO), can be generated from a wide variety of energy sources. Natural gas can be reformed in the unique, highly efficient MIDREX® Reformer or in a traditional steam reformer. Coal of any type or ash content can be gasified. Coke oven gas can be reformed using the MIDREX® Thermal Reactor System™ (TRS®). In addition, the export syngas from a COREX® Hot Metal Plant also makes a high quality reducing gas that can be used in a closely linked MIDREX® Shaft Furnace to produce DRI.
