Influence of Steam and Sulfide on High Temperature Selective Catalytic Reduction

Abstract: The influences of steam and sulfide on the efficiency of NOx reduction using ammonia (NH 3 ) 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 2 O at low temperature, but higher NO conversion efficiency is achieved at high temperature since the reaction of NH 3 oxidized by O 2 to NOx is inhibited by H 2 O. The activity of SCR is promoted by SO 2 in t… Show more
