질소산화물 제거를 위한 TiO_2계 촉매 제조 및 특성 시험

초록

One of main catalysts for De-NOx in SCR is a V_2O_5/TiO_2, and this work formulated powdery catalysts focusing ultimately on corrugate catalytic support. The prepared catalyst consisted of anatase TiO_2. Amount of the added vanadium oxide determined the viscosity of catalyst slurry, which is important for washcoat for a final corrugate type catalytic reactor. The test showed a proportional relation between adsorption amount of ammonia and specific surface area. De-NOx efficiency could be obtained up to 96.3 % at 400°C with a spacial velocity of 4,000 hr^(-1).
