Method of Determination of Parameters Included in ISHIDA-WEN'S Model

Abstract

A method of determination of the rate parameters (chemical reaction rate constant, effective diffusivity in the product layer and effective diffusivity in the reaction zone) and Thiele's modulus included in ISHIDA-WEN's model is proposed. With this method, those parameters can be determined easily from reduction data. This method was examined by being applied to the reduction curve calculated by ISHIDA-WEN's model and the experimental data of gaseous reduction of iron oxide pellets. This method was useful especially in the case of smaller value of Thiele's modulus.
