- Abstract
- The reaction kinetics which can describe the NH3 slip from a selective catalytic reduction (SCR) reactor as well as
the maximum conversion of NOx over a wide range of reaction temperatures has been investigated over a commercial
V2O5/TiO2 catalyst. The chemical phenomena are described by global reactions for the oxidation of ammonia and the reduction
of NOx using Langmuir-Hinshelwood reaction rate expressions. In order to account for the influence of transport effects, the
reaction kinetics is coupled with a fully transient one-dimensional monolith channel model. The steady-state chemical reaction
scheme used in the present mathematical model has been validated extensively with experimental data, selective NOx reduction
efficiency for a wide range of inlet conditions such as space velocity, oxygen concentrations, water concentration, and NO2/NO
ratio. We also performed parametric investigations to examine how the NH3 slip from a SCR DeNOx catalyst and the
conversion of NOx were affected by the reaction temperature, NH3/NOx feed ratio, and space velocity for feed gas
compositions with NO2/NOx ratios of 0 and 0.5.
