摘要：

The effect of flow behavior on degradation of de-NOx catalyst is experimentally and numerically investigated. The de-NOx rate for used catalysts is evaluated using laboratory-scale test apparatus, and the flow behavior in a honeycomb rectangular tube of the catalyst is studied by direct numerical simulations (DNS). The results show that the degradation of the catalyst is enhanced in the upstream region near the inlet. This is due to that the injected flow is a turbulent flow, which facilitates particles in flue gas to attach the catalyst wall, and the flow becomes laminar downstream in the catalyst.
