steel research international, Volume 91, Issue 12, December 2020., 2020 The Midrex direct reduction process produces a number of ferrous, fine‐grained residues. To avoid disposal, a way of briquetting the residues with binder and returning them to the Midrex direct reduction process is demonstrated. Laboratory‐scale briquetting experiments with inorganic and organic binders are presented and their suitability is compared ...

Green Hydrogen‐Based Direct Reduction for Low‐Carbon Steelmaking
steel research international, Volume 91, Issue 11, November 2020., 2020 Hydrogen‐based direct reduction is one approach to reach the goals of a future reduction of CO2 emissions by −80% in 2050. Process simulation models are presented to evaluate this technology. The implementation of hydrogen‐based steelmaking offers significant potentials for abating CO2, but simultaneously requires huge energy demands for the production
