Abstract

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 $400^{\circ}C$ with a spacial velocity of $4,000hr^{-1}$.
