抄録

Thiele's modulus for non-spherical particle is assumed by introducing the concept of non-spherical radius. Based on this modulus, Ishida–Wen's model for non-spherical particle considering the shape effect is presented. An example of the application of this model to the analysis of gaseous reduction of iron oxide pellets of various shapes is illustrated. According to the analysis result, Thiele's modulus for non-spherical particle is proportional to non-spherical radius as assumed while the rate parameters included in this model are independent of the size and shape of the iron oxide particle.
