内容記述 | In order to evaluate the performance and the energy requirements of the direct reduction process, reduction rates of cement-bonded cold pellets as burden materials were measured for reduction with H_2 or CO in the temperature range 873 to 1373 K. The results were analysed by the one-interface unreacted core model. The reduction rates were also compared with those of fired pellets. The reduction rates of cold pellets were greater than those of fired pellets under all conditions. The retardation phenomena which was observed during the latter stage of fired pellet reduction was not found in the reduction of cold pellets. It was found that a rate equation based on the unreacted core model could be applied to the reduction of the cold pellets based on the mixed control plots and observations of partially reduced pellets. The chemical reaction rate constants, k, were almost the same. However, the intraparticle effective diffusivities, De, of the cold pellets were considerably larger than those of fired pellets in the low temperature range, T<1073 K. | |||||
