This review focuses on the reduction of iron oxides using hydrogen as a reducing agent.
Due to increasing requirements from environmental issues, a change of process concepts in …

Hydrogen ironmaking is the most ideal approach to reduce industrial carbon emissions. In
this study, the isothermal reaction characteristics and multistep kinetics of hematite particles …

The reduction of iron oxide with hydrogen is a much-studied research topic, whose interest
is growing even more with the emergence of new applications, for example the hydrogen …

Carbon-free and sustainable energy storage solutions are required to mitigate climate
change. One possible solution, especially for stationary applications, could be the storage of …

Lignin and ferrous salt were mechanically mixed, melted, carbonized and steam activated to
produce magnetic bio-activated carbons (MBACs). Phosphate adsorption capacity …

Steel production using coal accounts for∼ 8% of global carbon emissions.“Green Steel” is a
new grand concept proposed recently to make steel from iron ores using renewable derived …

Gas–solid reactions are important for many redox processes that underpin the energy and
sustainability transition. The specific case of hydrogen‐based iron oxide reduction is the …

The activation of iron oxide Fischer–Tropsch Synthesis (FTS) catalysts was investigated
during pretreatment: reduction in hydrogen followed by carburization in either CO or syngas …

Hydrogen and carbon monoxide mixtures are reducing agents for main direct reduction (DR)
processes. However, sticking of iron ore pellets during reduction always leads to …

An integrated process that includes the pyrolysis of FeSO 4 dry impregnated lignin and
subsequent steam gasification of the produced biochar has been performed to produce H 2 …
