  Direct reduction of oxidized iron ore pellets using biomass syngas as ...

  201671 · The effect of syngas as the reducing gas on the reduction of iron ore pellets was similar to that of natural gas. The use of biomass during DRI production can eliminate CO 2 emissions, energy crisis, and climate change.

  Reduction of Iron-Ore Pellets Using Different Gas Mixtures …

  Direct reduction of iron ore (DRI) is gaining an increased attention due to the growing need to decarbonize industrial processes. The current industrial DRI processes are performed using reformed natural gas, which results in CO 2 emission, although it is less than carbothermic reduction in the blast furnace.

  Metals | Free Full-Text | Hydrogen Ironmaking: How It Works

  202063 · From mathematical modeling of the direct reduction furnace, we show that complete metallization can be achieved in a reactor smaller than the current shaft furnaces that use syngas made from natural gas. The reduction processes at the scale of the ore pellets are described and modeled using a specific structural kinetic pellet model.

  Kinetics of Direct Iron Ore Reduction with CO-H2 Gas …

  202238 · The reducing gas used in this case is nearly 95 % H2 and CO with H2 to CO ratio of 1.5-1.6 [4]. The basic HYL process employs a conventional natural gas-steam reformer for reducing gas generation. In this process, oxygen is removed from the iron ore by chemical reactions based on H2 and CO from the gas-steam reformer.

  Clean iron production through direct reduction of mineral iron ...

  2021121 · These results suggest that methane-rich hydrogen sources (e.g., coke oven gas) are viable options for direct iron carbonate reduction opening up a novel pathway for clean iron production from mineral iron carbonate with low-grade hydrogen sources.
