Abstract:
The selective catalytic reduction of NOx by propene under lean-burn conditions was investigated over Pd/Ce0.66Zr0.34O2/TiO2/Al2O3 catalysts supported on wire-mesh honeycomb and was compared with pellet catalysts and ceramic monolithic catalysts. The wire-mesh honeycomb possessed high geometric surface area (GSA) of 43.0 in.(2) in.(-3) and large open frontal area (OFA) of 86.6%. The wire-mesh honeycomb catalyst exhibited high NOx conversion at lower temperatures and could be stabilized in shorter time after temperature elevation than that of ceramic monolithic catalyst in the unsteady-state experiment. The wire-mesh honeycomb catalyst also exhibited characteristics of fast light-off. (C) 2008 Elsevier B.V. All rights reserved.
