In "The Norwegian Process Industries Roadmap", the ambition is that the metal industry shall have zero fossil CO2 emissions and increased production within 2050. Currently, no alternative commercial processes exist and there are few options for reducing the emissions. One of the most obvious is the partial replacement of fossil carbon with carbon derived from biomass.<br />The concept of the tailor-made biocoke for Mn production, which is hybrid reductant produced by use of coal-biomass blends, is developing within the Biocoke4FAl project between Polish-Norwegian cooperation. The main objective of this paper is assessment of tailor-made biocoke with charcoal additions up to 20% towards the production process for manganese alloys. The main properties of the reductants investigated are cold and warm strength, CO2 reactivity, slag reactivity and electrical resistivity are subjects of this paper. |
