  author={Daniel R. Parisi and M A Laborde},
In this work, the shaft furnace reactor of the MIDREX ® process is simulated. This is a counter current gas-solid reactor, which transforms iron ore pellets into sponge iron. Simultaneous mass and energy balance along the reactor leads to a set of ordinary differential equation with two points boundary conditions. The iron ore reduction kinetics was modelated with the unreacted shrinking core model. Solving the ODE system allows to know the c tion ( e used for d ©
