Abstract Scope |
Biocarbon will play an important role to achieve a carbon neutral and sustainable steel industry. In this study, three hydrochars (one type of biocoal produced via the hydrothermal carbonization process) derived from green waste, rice husk and orange peel were tested in a 10-ton test-bed EAF. These hydrochars were added to EAF (electric arc furnace) via injection and top-charge as carburizer to substitute anthracite. In general, the slag formed is good for the desulphrization process, and a better carbon yield can be achieved with hydrochar top charging. P and S level in metal could be controlled at an acceptable level. Perspectives of using hydrochar for EAF steelmaking is also presented. |
