Effect of Cordierite-Modified on SCR Commercial Catalyst

Abstract:

The V₂O₅-WO₃/TiO₂ honeycomb catalysts with cordierite modified were prepared by solid-liquid mixing method. Its thermal stability, crystal structure, abrasion resistance and activity were studied by XRD, abrasion equipment and simulated flue gas analyzer,respectively. The results indicated that V₂O₅-WO₃/Cordierite-TiO₂ honeycomb catalyst possessed a better thermal stability, mechanical property and activity at the higher temperature comparing to commercial catalyst. There was no rutile phase present after the catalysts were calcined at 700°C, and the vanadia and tungsten trioxide phases could be apparently visible on TiO₂. Key word:V₂O₅-WO₃/ TiO₂; Cordierite; flue gas denitrification; NO_x; selective catalytic reduction (SCR)
