A three-dimensional modeling of vanadium-based SCR catalyst is performed in this study. The processes in the gas phase, washcoat layer and solid substrate are calculated simultaneously with the assumptions of steady-state laminar flow and viscous gas in a single square channel monolith. The non-isothermal diffusion and reaction processes are calculated by suppressing the convective term of the species transport equation in the waschoat layer which is represented by a porous medium. The effects of pore diffusion and mass transfer on the gas phase are directly calculated in this fully distributed model. Eley-Rideal mechanism with the first order kinetic of NO conversion and NH3 oxidation is selected in this study with the ammonia gas as a reducing agent. The reactor performances are calculated and compared with the experimental ones at high and low temperature ranges. It is found that the temperature and concentration distribution along the SCR monolith channel can be observed in detail at the gas-phase, washcoat layer and the solid substrate for this 3D model.
