GASIFICATION AND THE MIDREX? DIRECT REDUCTION

iron ore reduction technology operates entirely in the solid state, then the product is called direct reduced iron, or DRI To produce DRI, the oxygen in the iron oxide is chemically removed by reacting with carbon monoxide (CO) and/or hydrogen (H2) at very high temperatures, about 900 COverview of Market for Direct Reduced Iron - 神戸製鋼所,58% of the direct reduced iron produced in the world is made by the MIDREX process (Fig 2) Direct reduction iron-making plants are much less capital intensive than blast furnace based plants and do not require coke either Because of this, developing countries, particularly natural gas producing countries, have built direct reduction iron-making plants for their own ironworksOptimizing DRI production using natural gas - MIDREX,Within the MIDREX® Shaft Furnace direct reduced iron (DRI) is produced by reacting iron oxide with a hot reducing gas made up of H 2 and CO The H 2 and CO reduces Fe 2 O 3 into metallic iron (Fe) and the by-products of this reaction are CO 2 and H 2 O In the MIDREX® Reformer natural gas is heated and catalytically reformed along with the recycled CO 2 and H 2
