A mathematical model for non-isothermal countercurrent moving bed was proposed and one of the numerical calculation methods was developed. The expression for the reaction rate included in this model was based on the unreacted core model, and the rate parameters were determined by using experimentally obtained rates of the reduction of single iron oxide pellet by hydrogen. The influence of the operating conditions on process variables in the bed was analyzed theoretically. At the same time, the experiments of non-isothermal countercurrent moving bed were carried out and the experimental results were compared with the calculated results. It was found that calculated values agree well with those obtained experimentally. The results were summarized as follows : 1) The proposed mathematical model was most suitable for the analysis of the obtained result. 2) It was found that the rate parameters measured from single iron oxide pellet could for the process-analysis of moving bed. 3) The longitudinal distributions of process variables in non-isothermal countercurrent moving bed cold be estimated with considerable accuracy.
