| Abstract Scope |
A novel ironmaking process that produces iron directly from iron concentrate without requiring pelletization/sintering and cokemaking has been developed. This process takes advantage of the high reactivity of the concentrate particles and will significantly reduce energy consumption and carbon dioxide emissions compared with current processes. The process of the development from the conception of the idea, to kinetic feasibility establishment, and to the operation of a prototype facility will be discussed. The prototype reactor operation has validated the design concept in terms of heat supply and residence time, and identified technical hurdles. When operated with hydrogen, the new technology would use up to 60% less energy in the ironmaking step with little carbon dioxide emissions compared with the average blast furnace process. When operated with natural gas, the novel technology is expected to decrease the energy consumption by up to 44%, and will reduce CO2 emissions by up to 51%. |
