Abstract
porous filters were manufactured using cordierite powder whose mean particle size was 200 ㎛, they were loaded with catalysts such as Pt, Pd, Cu, Co, La, V2O5 by vacuum impregnation method. And we investigated the activity of catalysts used for catalytic oxidation of VOC by passing toluene through catalyst-loaded filters. The porous filters had the apparent porosity of 62%, the compressive strength of about 10 MPa and the pressure drop of 15 mmHg at the face velocity of 5 cm/sec. The loading of catalyst decreased the porosity of the filters and increased the pressure drop and the compressive strength of them. Among the catalysts, Pt had the highest activity for catalytic oxidation and could remove more than 90% of toluene at 250 . Below 250 , the content of Pt catalyst had an influence on the conversion of toluene but didn't show any influence above 250 .
