This paper presents the main kinetic parameters for the reoxidation of direct reduced iron (DRI) samples in air under non-isothermal conditions and compares the data with isothermal kinetic parameters for a typical DRI sample. It is found that the non-isothermal activation energy (DELTAE) values are less than the isothermal DELTAE values. For coal based DRI, the non-isothermal DELTAE values lie in the range 20-35 kJ mol-1. For gas based DRI the value is much higher, about 55 kJ mol-1. For the reoxidation of DRI, the kinetic compensation effect (KCE) has been found to be valid.
