Substitution of Fossil-Based Carbon with Kraft Lignin In Aggregate Materials Used for Furnace Electrodes for the Metallurgical Industry
Short Introductive summary
The metallurgical and steel-making industries heavily rely on carbon in the form of carbon electrodes, carbon lining pastes, and carbon-containing oxide refractories. Carbon that is currently being used in these industries is derived from fossil resources due to its unique properties, however, it will be essential to substitute these fossil resources with renewable ones to lower greenhouse gas emissions. One possible feedstock for this transition is Kraft lignin (KL) due to its high availability and carbon content. Still, substitution of fossil carbons with KL remains challenging due to its high oxygen content, high reactivity towards oxygen and carbon dioxide, as well as the non-graphitizing nature of most biocarbon-derived materials. This work aims to partially substitute petroleum coke with KL in carbon aggregate materials and to determine the maximum substitution ratio by using various characterization techniques and by comparing the results to different industrial benchmarks such as calcined petroleum coke.
