Micro-fluidized bed reactor is a new research method for the reduction of iron ore fines.The reactor is operated as a differential reactor to ensure a constant gas concentration and temperature within the reactor volume.In order to understand the dynamic process of the reduction reaction in micro-fluidized bed,a series of kinetic experiments were designed.In the micro-fluidized bed,the use of shrinking core model describes the dynamic behavior of reduction of iron ore.And the apparent activation energy is calculated in the range of 700-850 ℃ while the initial atmosphere is 100% content of CO.
