ABSTRACT = {The influences of steam and sulfide on the efficiency of NOx reduction
using ammonia (NH<sub>3</sub>) over the nanometer-class V-W/Ti catalyst in conditions of
high temperature is experimentally investigated using a steady-flow reactor. The
results showed that selective catalytic reduction (SCR) is inhibited by H<sub>2</sub>O at
low temperature, but higher NO conversion efficiency is achieved at high temperature since the reaction of NH3 oxidized by O<sub>2</sub> to NOx is inhibited by H<sub>2</sub>O.
The activity of SCR is promoted by SO<sub>2</sub> in the temperature range of 200~500°
C, the NO conversion efficiency was improved to 98% from 94% by adding
SO<sub>2</sub>. SCR would be improved at 350~500°C when H<sub>2</sub>O and SO<sub>2</sub> exist at the same
time. Furthermore, the positive influence to the NOx conversion was proved in the
presence of H<sub>2</sub>O and SO<sub>2</sub> as a result of the European Stationary Cycle test.},
