  • Direct Reduction Process an overview | ScienceDirect Topics

    Direct reduction processes may be classified, according to the type of the reducing agent used, to gasbased and coalbased processes In 2000, DRI produced from the gasbased processes accounted for 93%, while the coalbased processes produced 7% GasDirect reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, ie without melting, as in the blast furnace The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal Iron ore is used mostly in pellet and/or lumpy form The chemical reactions involved in the direct reduction of iron are theDRI production | International Iron Metallics AssociationDirect reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (eg, natural gas) The solid product is called DRI and is mainly applied as feedstock in EAF The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed (2) Smelting reduction (SR): This involves combining iron oreDirectReduced Iron an overview | ScienceDirect Topics

    Abstract Hydrogen direct reduction has been proposed as a means to decarbonize primary steelmaking Preferably, the hydrogen necessary for this process is produced via water electrolysis A downside to electrolysis is the large electricity demand The electricity cost of water electrolysis may be reduced by using a hydrogen storage to exploit variations in electricity price, ie, producingThe hydrogen is produced by means of natural gas reforming, but hydrogen from sources other than a steam reformer, eg from water electrolysis, can also be used The first reduction stage is a circulating fluidized bed (CFB), the second reduction stage a fluidized bed (FB) reactor To heat up the fine grained DRI product to briquettingCircored hydrogenbased reduction minevik Outotec
