摘      要：An unsteady-state mathematical model describing the behaviors of gas and solid during the oxidation of ilmenite in a fluidized bed was developed on the basis of the two-phase theory of a fluidized-bed reactor. The longitudinal distribution of the concentration of gaseous species and that of the unreacted ratio of solid material in both bubble phase and emulsion phase as well as their variation with reaction time were determined by means of mathematical simulation with kinetic parameters measured experimentally, furthermore, the reaction behavior of particles with different size in a multiparticle system was also analyzed, and finally, the potential way for increasing the reactor efficiency was put forward.
