Decomposition of SO2 with CO reduced magnetite: Effect of

This work investigated the decomposition efficiency of SOsub2/sub with oxygen-deficient magnetite. The natural magnetite was grinded with wet ball-milling method to prepare sub-micrometer size magnetite powder. The powder was characterized by SEM and XRD. Oxygen-deficient Ferrite Fesub3/subOsub4-#x03B4;lt;/subgt; was reduced from natural magnetite in the CO gas
