1. Bio-coal as an alternative reducing agent in the blast furnace
Abstract : The steel industry is aiming to reduce CO2 emissions by different means; in the short-term, by replacing fossil coal with highly reactive carbonaceous material like bio-coal (pretreated biomass) and, in the longer term, by using hydrogen. The use of bio-coal as part of top charged briquettes also containing iron oxide has the potential to lower the thermal reserve zone temperature of the Blast furnace (BF) and, due to improved gas efficiency, thereby give a high replacement ratio to coke.

2. Influence of the properties of bio-coal as a substitute for fossil coal in carbon composite agglomerates and in coke
Abstract : The iron-ore-based blast furnace (BF) process is still the most dominant method for producing metallic iron units for steelmaking, and the BF is also the main contributor to the 7-9% of global CO2 emissions which, according to World Steel Association, originate from the steel industry. The steel industry is aiming to reduce CO2 emissions by different means. READ MORE
