Abstract	This work investigated the decomposition efficiency of SO2 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 Fe3O4-δ was reduced from natural magnetite in the CO gas flow. The activity of decomposing SO2 with Fe3O4-δ was tested by measuring the pressure variation of the SO2 system. The results showed that the activity of decomposing SO2 by oxygen-deficient magnetite appeared as a single peak in the range of input CO flow rate. Under the experimental parameters: the temperature of 673K, CO flow rate of 40ml/min and the reducing time of 6 hours, the CO reduced magnetite showed the best efficiency of decomposing SO2, that is, $1.414×10^{−3}mol$ (SO2)/g (Fe3O4-ゴ). New material (FeS2) appeared in the Fe3O4-δ powder during the decomposition process.
