Study on Catalytic Decomposition of Dioxins by Supported CeO2-TiO2-V2O5 Composite Catalyst

摘要：

Loaded on the cordierite, the rare earth doped composite catalyst was prepared by sol-gel method combined with dipping technique. Taking Orthodichlorobenzene as model, the catalyst was used to remove the dioxins of the waste gas. The results showed that at 280℃ and gas space velocity being 8000h<-1>, the orthodichlorobenzene could be removed effectivily by the prepared CeO<,2>-TiO<,2>-V<,2>O <,5> composite catalyst whose activity was remarkably enhanced by the doping of Ce, while the industrial side-stream test of dioxins from refuse incineration smoke indicated that the decomposition rate could reach above 93％ under the same conditions.
