H2 -based and biomass-based ironmaking : Inputs from modelling
F. Patisson and O. Mirgaux
We present two examples of breakthrough ironmaking processes studied at the IJL. The first one is the direct reduction in a shaft furnace operating under pure H2, the most considered and mature process with very low CO2 emissions.. The second process is also a direct reduction process in a shaft furnace, but without any input of external reducing gas. Iron ore and biomass lumps are charged at the top. The Boudouard reaction produces in situ the CO used for the reduction of iron oxides. The results obtained by numerical simulation of both processes are given and explained.
Fabrice Patisson graduated from the Institut National Polytechnique de Lorraine, France, and subsequently obtained a PhD from the same institution. He was for a long time a research scientist at the CNRS, Centre National de la Recherche Scientifique. His research topics have been gas-solid reaction kinetics, process modelling, and now concern the reduction of process impacts on the environment. He is currently Professor at the Ecole des Mines de Nancy, a component of the University of Lorraine, and responsible for a master's programme in the energy department.
