Wasserstoffreduktion

Reduktion in der Werkstoff- und Prozesstechnik

Wasserstoffreduktion

Wasserstoffreduktion bezeichnet die Reduktion von Metalloxiden oder Erzen mit molekularem Wasserstoff statt mit Kohlenstoffträgern. In der Werkstofftechnik dient sie zur CO₂-armen Eisen- und Nichteisenmetallherstellung sowie zur Dekarbonisierung thermischer Prozesse. Reaktionskinetik, Diffusion von H durch Oxidschichten, Phasengleichgewichte und mögliche Wasserstoffversprödung der entstehenden Metalle sind zentrale Forschungsfelder.
