Abstract
In order to improve the activation effect of deactivation catalysts, calcination of V2O5-WO3-MoO3/TiO2 catalysts were investigated. The experimental results demonstrate that calcination time have an effect for recovering the activity of V2O5-WO3-MoO3/TiO2 catalyst. Calcination not only ensures the better mechanical strength and integrity of the catalyst, but also plays an important role in the denigration activity of the catalyst. However, the particles of the catalyst surface enlarged with the increase of the calcination temperature. The suitable calcination time can improve the denigration efficiency and increase the mechanical strength of the catalyst. In addition, the calcination time mainly affects the formation of MoO3. These findings can provide reference for the activation of SCR-Den Ox catalyst.
