The effects of metal oxide supported catalysts on denitration and SO2-resistance were investigated. A series of metal oxide supported catalysts were prepared by the method of equal volume impregnation, and the denitration and SO2-resistance of different properties and structural catalysts were studied. The catalysts were characterized by XRD and SEM, and then the mechanism of denitration and SO2-resistance was analyzed. The result showed these: (1)7KHHJJRONX2Ȗ-Al2O3 supported catalyst had well denitration and SO2-resistance, and the denitration efficiency remained around 81 and 72 , respectively; (2) the denitration and SO2-resistance of egg yolk-white/ supported catalyst prepared by alkaline earth metal oxide was poor, the reason was that the insoluble substances were easily formed in the particles and blocked the channel, so the denitration efficiency was reduced; (3) In the catalysts prepared by eighth group of metal oxides, the efficiency of denitration and SO2-resistance of NiO-CuO/Ȗ-Al2O3 was higher than that of CuO/Ȗ-Al2O3. But comprehensive performance of NiO-CuO/Ȗ-Al2O3 was not as good as that of Fe2O3-X2Ȗ-Al2O3, the denitration efficiency of Fe2O3-X2Ȗ-Al2O3 remained around 83 and 79.6, respectively.
