【Abstract】 By using TPR and MBS,the reduction behavior of fused iron catalyst containing Zr is investigated. The influence of Zr content to reduction rate and original reduction temperature is obtained. For both kinetic model of reduction(contracting sphere model and solid reticulation model), the catalysts can be suited to them at different temperature range as different Zr content.更多还原
