The basic fundamentals, related to gas direct reduction, are analyzed. In order to produce carbon-free steel, hydrogen is fundamental.

This is a coal-based reduction technology, applicable to both steel mill waste and iron ore fines, with coal as a C-reductant agent. The reduced iron can be fed to a BF or directly into a melting process. If exposed to air for a long time, the metallic iron reoxidizes into iron oxide, deteriorating its quality.

Direct Reduced Iron (DRI), also known as sponge iron, is highly porous, much less dense than iron ore and sintered steel, and is used as a raw material in electric furnace steelmaking.[] DRI is expected to sustain compressive impacts during handling, stockpiling, and shipping, which tend to break down DRI into fines.

1 Introduction. The iron and steel industry as one of the biggest industrial emitters of CO 2 accounts for approximately 30% of the global industrial CO 2 emissions. As set in the Paris Agreement, the emissions of greenhouse gases have to be reduced by 80–95% until 2050 compared with preindustrial levels to keep global warming below 2 °C.

Direct Reduced Ironmaking (DRI). Carbon combines with the oxygen in the iron ore, producing metallic iron and a carbon-rich process gas, according to the following simplified chemical reaction: 2Fe 2 O 3 + 3C -> 4Fe + 3CO 2 It is also possible to reduce iron ore using hydrogen instead of carbon; in this case the waste gas produced is water, as

There is a growing need to reduce CO 2 emissions from iron & steel production to prevent the worst effects of climate change. One of the leading technology options is using low or zero carbon hydrogen as a reducing agent in a direct reduction (DR) plant and subsequently such low or zero carbon power for

Direct reduced iron (DRI) is also known as sponge iron (Hasambeigi et al. 2014 ). This high porous material has a metallization degree in the range 85–95% with a carbon content in the range 0.5–4% depending on the processing route. During the process, the iron oxides are reduced at the solid state.
