摘 要：The reduction process of ilmenite by hydrogen and methane under MPCVD was analyzed by XRD result. The reduction degree of ilmenite increased with adding methane, the case similar to reduction rate. The mechanism of reduction process changed with the increasement of methane flow because of the formation of carbon nanotubes （CNTs）. The morphology of reduced samples was observed by SEM, and it was found that CNTs played an important role in the fracture of ilmenite particles. The reduction kinetics showed that the reduction was rate-controlling for hydrogen, and diffusion-controlling when hydrogen mixed with high flow methane.
