Carburization in direct reduction: Effects of various CO-H2 gas mixtures
https://doi.org/10.1016/j.partic.2026.04.014

Highlights

  • Pure H2 gives fast reduction, full metallization, and a dense uniform α-Fe structure.•

  • Pure CO exhibits slow reduction and forms iron whiskers at 1273 K with minimal carbon.

  • H2/CO forms carburized structures, which potentially hinder reduction.•

  • Simulated biogenic gas attains high metallization with controlled carburization.•

  • The 1D porous-solid model links oxygen removal, carbon uptake, and carbide formation.
