Abstract Scope |
Graphite electrodes are essential to the EAF process. We’re proposing an innovation to the operation of EAF, by introducing graphite electrodes made from carbons sourced from carbon dioxide (CO2), instead of being sourced from fossil-sourced carbons (petroleum needle coke). This innovation has the potential to significantly reduce the net carbon intensity of the EAF process, specific to the emissions from the graphite electrodes. By converting carbon oxide gases (CO + CO2). The carbon oxide emissions from the oxidation of the graphite electrode would be offset by the sequestration of CO2 into the solid carbon which is the precursor for the graphite electrode. Tokai Carbon, a leading manufacturer of graphite electrodes for EAF currently uses the traditional petroleum needle coke feedstock as the carbon precursor for the graphite electrodes. In this project Tokai will use this new CO2-sourced carbon as the carbon precursor, with in-situ performance of the electrodes by Nucor. |
