porous filters were manufactured using cordierite powder whose mean paricle size was 200㎛, they were loaded with catalysts such as V2O5, CuO and LaCoO3 by vacuum impregnation method. And the NOx/SOx simultaneous removal efficiency was measured by passing NO and SO2 through catalyst-loaded ceramic filters. The cordierite porous filters had the apparent porosity of 61.6%, the compressive strength of 12.3 MPa and the pressure drop of 147 pa at the face velocity of 5 cm/sec. According to the analysis of NO/SO2 simultaneous removal efficiency, perovskite LaCoO3 catalyst was the most efficient for the simultaneous NO and SO2 removal. The LaCoO3 catalyst-loaded filter could remove more than 90% for NO and more than 80% for SO2.
