202139 · Context & scale This paper explores existing approaches and potential decarbonization paths of the global iron and steel industry: fuel switching to low-C hydrogen, solid biomass, zero-carbon electricity substitution, and retrofit with carbon capture and storage (CCS). Achieving net-zero primary production with current available technologies …

Wastewater from this process contains metals, suspended solids, benzene, and fluorides. These degrades the soil and water bodies as the sludge is disposed in the environment [ 14 ].

It aimed to investigate the reduction behavior of Fe2O3 in undiluted CH4 flow to establish the process parameters for sponge Fe formation. Thermodynamic analysis predicted the reduction of Fe2O3 to Fe by CH4 at 1000–1200 K. The …
