Substitution of Charcoal for Coke Breeze in Iron Ore Sintering
1. Introduction. Iron and steel production accounts for about 70% of world greenhouse gas emissions generated from primary metal production. 1) While there are a number of short term approaches to reducing CO 2 emissions from iron and steel production, the longer term approach will require gradual substitution of fossil fuel-based energy and reductants such as coke and coal with renewable ...
